I agree clique thing is a bit beaten to death... Although it doesnt really bother me, mostly because there cant be that much wrong with people that want to fight with sharp pieces of metal and sticks, rather than glowy fantasy BS.
The chat? Theres always a bunch of a-holes in all online games that are desperate to sound cool while making complete fools of themselves, nothing new.
To someone who's never played games online, we'd look like complete nobs. to someone whose played a few, when you cut through the surface bs, its actually much better than most.
