We used to have clans for the first couple years the game was out, but it became kind of pointless after a while. The reason clans don't really work is that the community is so small, it is almost impossible to get a clan vs clan fight going, and a bunch of random people are not going to fight a clan team, even if we did 4v6 or occasionally 3v7. Since people tend to prefer to pick teams, there was no real advantage to being on a clan.....in fact, once picking teams became the most common way to play, smurfing became the meta strategy to gain an advantage rather than trying to play as a disciplined clan team.
