We can’t be sure when we'll see flying in Battle for Azeroth, but it helps to be as prepared as possible by completing the available achievement Battle for Azeroth Pathfinder, Part One to ensure you’ll be well on your way to fly the less-than-friendly skies when you can. In the meantime, earning this achievement will grant you increased passive mount speed on Kul’Tiras and Zandalar.  Here’s what you can do to work your way towards unlocking flying in World of Warcraft's Battle for Azeroth!

If you find yourself coveting your first mount, and with no money to purchase it, try to swallow your frustration and work at earning and saving up so you can buy it honestly. Nothing is more annoying to other players who are working hard to earn their own money than hearing someone begging for gold so that they can buy a mount or fancy piece of gear.
Assuming, worst case, procs of 30 monelite ore, in my server they sell for 20g each, so 600g per proc. 5325 divided by 600 is 8.875 missions, rounded up, 9 procced missions in order to make even with pick costs. EVERYTHING after that is pure profit. Its important to remark that the chance is far from 100%, some people say as low as 10% to proc but I didnt find any hard data on this.
Once again, as soon as you hit 70 - I recommend to go and learn faster flying. This speeds up your questing A LOT, and is worth the time and gold. It will cost 4500 if you go to the capitol, or 5000 if you prefer Shattrath/Dalaran, because you will not have reputation with them at that point. This price will sadly be above what a totally new character can afford, if you don't have any Main. But you should go and buy flying as soon as you have enough money.
Was doing it at 52 on my lightforged paladin and it was easily the slowest zone out of the ones I'd done. Granted, I didn't have War Mode on so I didn't have any PVP talents, but it felt like about 40% of my time was spent waiting around for respawns or wandering around looking for mobs to kill to get a quest item that had like a 5% drop rate. Maybe I just got unlucky but I definitely won't be going to that zone again for future heritage armor runs.

This is a once size fits all pet farm that can generally leave you with a small sum of gold if your server is low on this specific pet. (You can always check on the undermine journal).  It takes place in the Ihgaluk crag and is generally performed by sweeping the oozes in the small muddy pools surrounding the area.  An easy spot to hit, that really isn't farmed all to often.  I was able to get one in the video after a small 24 minutes.
Level 120 comes and goes. Island Expeditions have unlocked, but it turns out they’re not much fun, and the most rewarding versions are only accessible to premade groups. You turn to Warfronts only to realize they’re not available this week. Fine. You can always grind out better gear. Except as you do, you notice your new gear has higher Azerite requirements than your old gear, which means your shiny new items have fewer unlocked traits than what they replaced. Discouraged, you decide to roll as one of the cool new Allied Races. Except you can’t because they’re all locked behind reputation grinds.
Allied races aren’t much better. You can only earn them by grinding out reputation. It doesn’t take that long but casual players will need to invest a couple weeks primarily to it, and focusing on that grind will take you away from others, like earning gear. Each race has its own grind, but the things you do to work through it remain the same, adding to your boredom.
The greatest potential for going from 25,000g to the gold cap of 214748g is transferring servers. However, this also presents the greatest risk and needs the most preparation. First off, transferring costs money. If you go to a server, transferring back as soon as the cool down is up is expensive and impractical. You should look for a server that you can stay on for at least 6 months to a year before transferring back with your huge profit. However, the maximum amount of gold that a max character can transfer is only 20,000. Therefore, you need to purchase goods that are going to net you the most profit when you go to sell them on the new server's auction house. Primarily, these are enchanting mats, but can also be BoE epics depending on the two servers. Before making a risky decision such as transferring, consult the questions below.
Similarly, when earning by volume, do not overload the AH with your items. Basic supply and demand: too much supply will make your wares too common and unwanted. Furthermore, with great demand and a cheaper price, you may end up starting a price war with your competitors, with them actively trying to undercut and outdo you. Moderate the amount of items you're selling on the AH to small batches, refilling them only when sold out.
The neutral auction house can become one of your best friends. Other players are constantly checking both factions' auction houses to find an appropriate price for the good they demand. Often times, goods are cheaper on the alliance because they have more people, thus, the supply increases as demand decreases and price goes down. If you are horde, feel free to transfer gold to your alliance toon through the neutral auction house in order to buy them item and bring it back to the horde side where it is more expensive. The 15%, as of patch 3.3.3 (down from 30%) is well worth the extra 50% or more you can easily make on one item alone. Blizzard decreased the neutral cut for a reason to 15%, that reason is to get trade facilitated between the horde and alliance. Make sure you take advantage of this! Tips when trading between factions:

-PvP- Completely broken for some classes and I mean broken going from both sides of the spectrum, from classes destroying everyone, to classes that can't even kill another player. It's fairly common for a weak class to lose to a powerful class even if the weak class outgears them by 50+ ilvls. That's how broken PvP is and Blizzard doesn't seem to know what to do to fix it other than do blanket damage nerfs/buffs as those are the only changes we've seen.
If you are just coming out of Level 110, you will probably have a number of different Legendary items to choose from. Your Legendaries' special effects will stop working at Level 116, but until then, they can be a very powerful addition to help you level up quickly. These are our Legendary recommendations for leveling as an Enhancement Shaman in Battle for Azeroth:
I like his recommendations 2 level 1-20 zones to get to 20, then do all the 2nd zones since they are designed for walking (Horde: Northern Barrens, Silverpine Forest, Ghostlands, Azshara, & Hillsbrad Foothills if you need a little more. Alliance: Westfall, Loch Modan, Darkshore, Bloodmyst Isle, and if you need a little more Redridge Mtns, or Duskwood). Don't even bother with the higher level areas, too spread out. Finishing up a Monk now and I had done all these zones before the update, the running between quest and the 50% experience cap is driving me crazy.

The World of Warcraft playerbase is cut in half, but not in the usual “Horde versus Alliance” fashion. Instead, Horde players themselves seem at odds with what their faction actually stands for. Cobo and Lo suggest that this mismatch may be hard, if not impossible, to fix. Someone is always going to be disappointed, and with Cobo’s talk of honor being at the center of the Horde, Sylvanas-stans will probably have a disappointing time with the expansion.

Weak Auras is the most important AddOn for players seeking to master their class and take their gameplay to new heights. If you aspire to do any Mythic raiding, this is the most powerful tool in your kit. Weak Auras allows you to display helpful visuals cues anywhere on your screen, which enable you to play better. Most players use it to track their trinket procs, highlight on screen displays of their most important cooldowns, or track the timers of boss mechanics. It is highly customisable and makes keeping track of your procs and cooldowns effortless. The drawback of Weak Auras is that is has a bit of a learning curve and is not the most user friendly. Weak Auras allows you to import other players data directly into their UI, however, and most players choose to simply import other people's Weak Auras rather than make their own. Weak Auras can be used to create just about anything you can imagine, as it is a LUA scripting tool (essentially an AddOn that creates other AddOns, in-game). This is by far the most essential AddOn for players looking to step into Mythic raiding.
Step-by-step class guides are on the way!  The 1-12 Mulgore Guide is the first guide to get all the individual class steps.  At the top of the guide, simply select which class you are playing and the page will dynamically update all the steps in the guide for that class (both text and images).  The rest of the guides will be slowly updated overtime to include all the class steps, but you can see how it's going to work with the 1-12 Mulgore.  I want to thank crazyK and his Placeholderguild for helping me out with the individual class content.  They are allowing me to get the 1-60 Alliance guide done while also getting all the class steps done at the same time, so everything can be ready for Classic launch (hopefully).
Leveling used to be a treat in WoW. New, unique abilities drove you forward and made getting past the horrible grind worth it to some extent. Now it just feels like everything is set to grind. More than it used to be. Once it was tolerable, rewarding even, but now you grind to unlock an allied race through reputations barely connected to most of these races, only to have to level up that character to get their unique armor set (compelling you to not just boost your character and instead suffer through the slog of ANOTHER group of alts), then you get back to current content and grind some more with a random chance to drop the item you need to get your ilvl up to finally enjoy the single warfront available (as I write this).

Players’ relationships with the NPCs around them have been hit-and-miss over the years. One of the original issues with Thrall, the Horde’s original Warchief, is that players began to refer to him as “green Jesus,” because of how infinitely powerful and infallible he was. But he’s been gone since the Warlord of Draenor expansion, and with the death of Varian Wrynn and Vol’Jin at the start of Legion, the old guard hasn’t been there to guide players the same way as it used to be.

A common mistake of new players is to upgrade their gear at every opportunity, paying for a new piece even if it will only add one or two new stat points over an existing item. Likewise, investing in headgear, neckwear, trinkets, and rings at the earliest available levels can also consume valuable cash. While it might seem foolish to leave an available slot empty, you will eventually find something to fill it. Blizzard will see to it via the quest rewards you'll get along the way. In the mean time, the 1 or more you save will serve you well if you invest it wisely. The bottom line is that one can easily level all the way to the maximum relying on just quest/drop greens. The gear you get from regular questing can help you perform well in dungeons, which gets you even better equipment.
Majority of world quests provide pretty bad rewards. Running for a wq that rewards 130 gold is a waste. Resources are not that necessary apart of some rare profit missions or buying the seal for them. Azerite for non-raiders or nonmythics is pretty much useless to farm since every patch will lower their requirement, and aside from few occasions it brings not much of a value. Not to mention that island expeditions are probably easier/faster with rng chance for tmog or pets. So the only main reason to farm them is the reputation. The most important is getting to exalted for recipes but for that there is no cache. The rest is pretty much not needed.
