The community is one of the reasons I quit playing WoW in the first place. Raiding and playing with your friends is fun, but having to rely on one or two people outside of your own group is hell. Also LFG/LFR was always more of a choir than heroics.

About the only online, community driven game I play nowadays is League of Legends. Most of the community is trout players that you cannot escape but I have dealt with so many of them that I don't even care anymore. Winning is fun, but losses don't even matter now.

Most people aren't even dicks. They're just absolutely atrocious at the game. Like an ADC (whose role is to essentially sit behind everyone else and auto attack) who cannot do his job right. Or the jungle (who shows up in random areas on the map to ensure kills for your team) who dies to one of the neutral mobs on the map (which is pretty smurfing difficult to do).
