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.
Most classes in World of Warcraft start at first level, but Death Knights and Demon Hunters are exceptions. They start at level 55 and 98, respectively. This alone can shave a huge chunk of time from your leveling experience. Of course, it only works if you want to play a Death Knight or Demon Hunter, but they’re both solid classics that can dish out damage or tank in a group.
I'm very, very interested in a guide that takes into the following: 1) Dungeon finder; and 2) Heirloom items. I've never helped with a guide before, but would be open to help in collaborating on the project. With the leveling guides I've used (primarily this one) I, too, find that I level at a rate that throws the pace of the guide way off (not its fault at all, I can't say enough good stuff about the guide) to the point that I get frustrated and just queue up for dungeons.
For those interested in more details on spending wisely, and generating good cashflow, we cover a number of topics in more detail. Please note that this guide represents the accumulated wisdom of many people. You don't necessarily have to do all of these things--there is no one "right" way to make and manage money. However, these pointers will give you ideas on how to establish a firm financial foundation for your character.
This leaves players chasing an endless loop of trying to get higher level Azerite gear — which can only reliably be gained through raids and isn’t available in Mythic+ — but only the pieces with exactly the right traits will actually be an upgrade. It’s even possible that some items that should be huge upgrades are nullified by the loss of a specific trait that makes one ability do more damage than the others.
Different qualities aren't limited only to wild pets—many rare World drops and special non-wild companions have had their stats boosted. For example, the world-drop dragon whelps (Azure Whelpling, Crimson Whelpling, Dark Whelpling, and Emerald Whelpling) are of [rare] quality. Check your Pet Journal to see the color-coded rarity of your non-wild pets.
