PS: as a side note i find it VERY funny that this discussion in some corners talk about max underrepresentation of Rogues and about overpowered Warlocks. the thing i find funny in that is the fact that over all 15 years Warlock was the most underrepresented class. long ago there was even a blue post from Greg Street (GC) about that and you can check it in the Census archives or wowprogress etc.
i wanna say totally nothing with that. and no, i play not a lock (i hate them of all my classes the most). i just find the relations funny.
