Nope,

No guides.

Prepare, it wont be fun 70-80. You will have to do a lot of collection quests and do around 8-12 hours a level. But the fun is worth it on 80!

If you're thinking what can i clear heroics with this expension its 1 tank 4 shamans. Instead of 5 shamans in TBC.

I hope this was useful,

Kind regards
