Implying horde pugs will ever get anything higher than 10% win ratio at 80... Just get real mate, everyone who intends to pvp a lot is human unless that class cannot be human, you still haven't seen the most ******ed of them all : the human dk
typical wotlk alliance ab bg comp: 3 rets 3 warriors 4 dks and 5 pocket healers vs 14 horde in full pve gears and a healer wasting his time trying to salvage the situation
your point is not really good either... You get pve gears that are "better" but when you meet that ret in full pvp gears while lvling in borean thundra get who is gonna get raped. Also get who is going to lvl faster anyway, you or the ret who does aoe 10 mobs in 2 seconds
Point is, just do whatever you enjoy while waiting for wotlk launch , a lot of people enjoy doing pvp, not for the gears but for the pvp itself. If you think doing extremelly simplifiec overnerfed raids is actually more fun, that is your point... You are always welcome to queue for a bg and get yourself farmed
