One team to annoy them all.

[Altsoba]

I'm currently leveling 4 Warlocks and true that they lack the support heal that shaman have.

They can get healed with their damage but I'm also attemptively looking at herbalism. It seems that next patch, lifeblood is going to get buffed and will be related to hp as in 3.2. Others speak just about tooltip clarification. I will only level their professions when they ding 80 so I have time to see.
The 4 fear spam with target=arenaN can also be interesting but I still have yet to try... well as any other thing btw Only theory...
