I have a PvE-team at 65 with a priest + 4 warlocks. Now I'm thinking about turning these into a PvP-team instead.
Should I go on with all 5 or only the warlocks?
Which pet is best for maximum single target dps? I'm thinking about imp or felguard, which is best for PvP?

I'll mostly play Alterac valley and Isle of conquest with these, since I always feel a bit uncomfortable joining with so many chars in smaller team battlegrounds.
