I play alliance. The reason for it is cosmetic as i just don't like how the horde looks(with the exception of Orcs ofc). I just like the alliance look better, simple as that.
The community/maturity is pretty much the same on both sides, i know some people claim the faction they're not playing is alot more immature etc but this is probably just due to the fact that within their own faction they play with a group of people that suits them and ignores the immature/ idiots. But if you roll a new char on the other faction you'll have to start getting to know people again from scratch(and sorting out the jerks and aholes again).
