All starting zones includes all class steps. The 12-60 Horde contains all the Hunter, Warlock and Warrior steps. The 12-60 Alliance contains all the Hunter steps right now. You can still get a LOT of use out of the leveling guides even if your class's steps are not implemented yet, you will just need to do those few class steps on your own for now.
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.
Some quests in my guide are marked as "SKIP" and colored in red. These quests are simply either too hard to solo or not worth the XP/time and are skipped. My guide will only list SKIPPED quests if the quest is a direct follow up after completing a quest, not one that you have to click the NPC again to get it. If you hover over the skipped quests, it will give info on why it is skipped in the guide (unless that info is already listed directly in the guide text).
