EXCEPTION: If you have Mining and only use Jewelcrafting to craft stone statues (for additional in-combat healing), then this may be a useful tradeskill. However, like Engineering above, it should not be a leveling focus and should only be used to assist with power leveling. Doing any more than this will become costly and should not be undertaken during the power-leveling process.

Most of the time you spend leveling will involve questing and slaying monsters, but there’s also a lot of travel. Travel earns you little experience (you do gain a bit for discovering new areas), so it’s wise to keep travel to a minimum. The new level scaling system, which scales zones to your level within a preset range, helps with that. You can choose what zones you want to experience and stick with them until you finish their quests.
I am currently working full time on my Vanilla WoW leveling guides.  Soon there will be a 1-60 speed leveling guide for Alliance, along with in-game guide versions available for my members area.  As of right now, there is no members area, but if you would like to show support for my efforts into this project, you can simply donate to me via Patreon if you like (you will get some cool rewards in return).  Or you can donate directly with PayPal if you like.  All donations are highly appreciated and they will only motivate me more to continue making the best vanilla WoW leveling guides on the web.
"The way the glyph market works on most realms is that there are a couple of people willing to put in the long hours who will have every available glyph posted profitably, and undercut within minutes of being undercut. They all reduce the price very minimally when undercutting, and the "competition" isn't about price, it's about who can relist more frequently.

Like most of those experienced players, I had all the benefits, including a full set of heirloom armor, which helps to boost the experience my character would get (though that bump was reduced at the same time the other changes were made.) I had a guild, the ability to fly in every zone, and pets and toys that made a pile of things more convenient. My new character started at level 20, as all allied races do.
At Level 78, you unlock the stat Mastery, which increases your Shadow damage. When you unlock this stat you should switch your level 56 talent from All Will Serve to Clawing Shadows, as it benefits more from the Mastery. The mechanical change when using Clawing Shadows is that you will be able to pop Festering Wounds from a distance. If you want to attack multiple targets with Clawing Shadows using Death and Decay's cleave effect, make sure you play the Death and Decay below your own feet instead of the target.
I hope this information helps a lot for players that haven’t had the chance to play Beta and gives you an idea of what you should be trying to accomplish your first 2 weeks of BFA. If you plan on pulling all-nighters, please don’t be reckless and over strain yourself. People have died from lack of sleep. If you want some tips on staying up I recommend taking a nap before launch time, eating a healthy meal full of protein before launch, snacking on fruit and nuts (my personal go to is clementine oranges and almonds) while leveling, if you do decide to drink energy drinks I do recommend not getting the ones packed with sugar (I prefer no sugar no carb Redbull and G-Fuel) and making sure you drink at least 2 bottles of water in between every energy drink so you stay hydrated and don’t crash. A good time to get some sleep is after you finish all the questing and you are 120 which again will take average played 10+ hours. Again, please don’t be stupid and end up hurting yourself over a video game; everyone must sleep at some point, so you won’t be too behind the curve.
I made one for my guildies but its for the Horde leveling process. One tip that goes for both factions is that you dont need to do all 3 zones to hit 120. I did like 1 and than three quarters of another. But once your 120 you need friendly with all 3 of your factions new reps to unlock world quests so make sure you hit at least friendly with all 3 while your leveling.
