Here's the first of my 3 top legion skinning farms.  They are my favorite for a reason – with the right skinning perks, you can make thousands more gold than the average farmer.  Overall, these are the most profitable legion farming spots, period.  With the oddly shaped stomachs drops you can get access to leylight shards, leystone ore, and felslate along with a variety of other highly-liquidable trade goods to boot.  In order to get these tiny treasure chest like stomachs to drop, you need to get your hands on the gutting perk, which can be purchased by trading 250 sightless eyes at the quartermaster in the dalaran sewers.  On the other hand the butchered meat drops will award stormscale and stonehide leather, making these skinning spots some of the most gold healthy spots in the entire game.  I hope you all jump on this.

Another potion of treasure finding farm that was made extremely popular by the YouTuber Oldbess.  In this spot, you are simply to patrol the entire southen river basin in Twilight Highlands, just around the Verrall Delta area.  The goal of this farm is to kill water elementals for their volatile water, which trends around 50g per drop.  Combine this with the cloth and the treasure chests, and you have a cool  nifty farming spot – thats rarely populated these days.
Once you have your potions, proceed to complete all the bonus objectives in your starting zone. This should easily level you to 92, where you can proceed to Gorgrond. Interesting enough, for some reason many Gorgrond quests are worth nearly double the experience of quests in other zones. Maybe this is a bug, maybe intended, I'm not sure. But I actually recommend you do all the quests and bonus objectives in Gorgrond. For your outpost choice, I recommend choosing the Gladiators, since they give access to more treasures than the shredder IMO.
Taking Herbalism and Mining as your two professions can be a lucrative way to level with the very stable and high prices of herbs and ore thus far in BfA. While rested, each mining and herbalism node will award nearly 4,000 experience points which makes it so that four to five herbalism or mining nodes is equivalent to one quest. If you have the Sky Golem mount for herbalism, you can pick herbs without losing mount speed. There are also enchantments for gloves that will increase the speed at which you can process the herbalism and mining nodes. These can be made rather easily by an enchanter and should be relatively inexpensive on the auction house. These enchants will pay for themselves with the time saved while herbing and mining. Remember to continue completing mining and herbalism quests while leveling up to increase the yield of each node making your herbalism and mining leveling experience exponentially more lucrative.
To give you some perspective I leveled both a LF Ret Paladin and BE Rogue (so one started from level 20 and the other from level 1). I focused on getting the achievements I was missing for the Loremaster, so not the most efficient route by any means. I was using full enchanted heirlooms (minus the ring) and the WoW-Pro addon though, as well as having War Mode turned on all the way.
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.
In World of Warcraft, establishing a monopoly proves much easier than the real world because of less competition and increased laziness from the consumer base, which increases demand through the roof. These factors are easy to exploit with proper preparation. Downloading and installing the following addons from your most trusted website is the first and most important step in the gold making process.

Crusader's Direhorn (Zandalari Troll Paladin Mount) Paladins have been confirmed as a playable race for Zandalari Trolls in Patch 8.1.5 and while the lore surrounding the class is not certain yet, it has something to do with Kimbul, not Rezan. Anyway, the class mount is Crusader's Direhorn, a gold-plated dinosaur. World of Warcraft WoW Yesterday at 13:06 by Stan 11 comments
World of Warcraft offers a lot of ways to make money (gold). There is no one "right" way to make money, although there are some definite wrong ways! Some people like to play the Auction House, some people do their daily quests, some people tend to farm, etc. Many characters do a combination of all three of these along with other activities. Below is a compendium of money-making methods.
YouTuber Oldbess recently uploaded a video about this cool method.  Generally completing the scenario "Deaths of Chromie" will allow you to pick up the item "Time-Lost Wallet" in excess.  You can get it from just killing the mobs or actually completing the scenario in full.  By then end you will have dozens of time lost wallets.  Each wallet awards 50g AND a rare chance at getting the ]bronze proto-whelp[/U] pet.  In the video, this spot was VERY hard for to pull off as it requires a high item level.  With an 809 item level I struggled all throughout the scenario and could not make this spot profitable for the time invested.  The good news is, if you can get it done, the gold you make will be entirely liquidated – the rewards are 50g raw for each wallet turn in.  I suggest you watch it on Oldbess's channel for full details.

World of Warcraft has been around for a really long time now. While the gameplay, graphics, and story have enhanced over time, the UI has not changed nearly as much. Some things that may seem like they should be obvious menu items are only accessible via addons. Addons in World of Warcraft are essentially mods that give you additional menu options and visuals. Some are small, and mostly used for organizing items or menus, while others will give you more options in combat! Below are some of the best addons for both old and new players. The majority of these can be downloaded through Curse.
The most important step in being able to buy a mount and make other large purchases should be self-evident: saving. Economize as often as you can, and don't buy anything unless you absolutely have to. You can burn through hundreds of gold even before level 20 by visiting the auction house for new equipment at every opportunity. If you do so, over the long haul you will be left with very little to show for it. Before level 20, keep your eyes on the prize: getting that mount. The mount helps you move faster. Faster movement means faster killing, faster questing, faster quest turn-ins, and faster leveling. It is the most important tool to fast leveling you can get at level 20, and infinitely more important than getting your hands on that Left-Handed Vorpal Cleaver of the Zipswitch that you could have purchased at level 23. Stay focused.
Some players even turn this into their profession by systematically "plundering" vendors in the game world and then selling the items on the auction house at a significant markup. The reason why this works (even for items which are on unlimited supply at vendors) is, that many players don't want to spend time traveling to specific vendors to get hold of a recipe or skill book. They would rather pay a slightly higher price at their local auction house. In some sense, they use the auction house as a "super market" or "convenience store". So it is completely reasonable and legitimate to be the supplier for this convenience store and make money out of it.
 Void elf - "Many have sought to harness the corruptive magic of the Void. Most who tried have fallen into madness. Determined to use this power for the good of Azeroth, Alleria Windrunner is the first mortal to succeed at defying the shadow's whispers. Coming to the aid of a group of her kin who nearly gave in to the darkness, Alleria has vowed to train these Void Elves to control the shadows within them and pledge their newfound powers to the Alliance."
Your server population may determine how much profit you can make. Lower population servers generally have lower prices in the AH as there is less demand, but rare items or recipes can really make a profit as they are harder to come by. Higher population servers have a higher demand. However, they are more likely to have a flooded market, which makes items hard to sell, especially in the case of low-level gathering professions.

At Level 18, you unlock Freezing Trap which is a long-term crowd control for all Hunter specs. It places a trap on the ground that encases the first enemy (not bosses or most big encounter adds) to touch it in ice for 1 minute. The effect breaks on damage. The trap has a 30-second cooldown, and the trap will exist for 1 minute after placing it. This is useful when you are feeling overwhelmed by too many mobs, for temporarily taking out a powerful mob from the fight.
If your pet's health gets too low or its attacks aren't very effective against a certain combatant, you can always switch out your current pet with another companion on your team. Only pets that are considered active (i.e., those in your three Battle Pet Slots), may be switched in and out during the battle. Once the match is over, you can always change up your active pet team, which is useful if one of your pets is low on health or dead.

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.

I recommend not counting on transmog sells for your monthly gametime. Its a great market, but also pretty random. You have to have the right items posted at the right moment if a player needs a certain item. If this is not the case, of course you will not sell anything to him. There are people making millions of golds a month with transmog. But they are very professional at it and it really takes a lot of time.
