Wich expansion is best for PvP players. I mean in Warmane wich expansion is most suitable for PvP, battlegrounds mostly. Also in wich expansion classes are most balanced. For exaple I know that in TBC Sl/SL warlock are OP or something like that. I know that I can google this stuff but I also know that Warmane is bit buggy and not all things work as they should be.
Thanks for your help.
