I'm coming in late to this discussion but i feel its pretty balanced personally. The only issues I see are the ones mentioned by the rest of you, jumping into a game with a group of 4 then having people leave and carrying 4 bad players.... more then likely its a loss but sometimes you can pull one out.
Although, i believe this happens on both sides and its really queuing mechanic issue and not specific to any guild/group of people.
Even when I get my *** handed to me by a decent group LD50 et. all good PvP oriented guilds, it is far more fun then just smashing a bunch of scrubs who have no idea what they are doing --- don't get me wrong that is fun every once in a while but meh it gets old.
Here's to hoping the PvP Queue system gets revamped and they make leavers take a penalty from queuing!
