Clans are for... Power!!!BWAHAHAHHAAHAHAHA!!!

*has power overwhelmed eyes*

er... j/k i personally joined/co-founded A$ cause i wanted to get in on da clan war action... cause those are HECKA phun!

Of course, looking at it at a psychological angle, MOST, repeat MOST people join clans to try to fit in or get thier piece of power, beacause they feel thier power is too small, and they figure if they join a clan, or "wolf pack", as one could say, they feel more powerful.
