Interfering with gear = people can't wear full plate all the time because they can't afford it?
Intefering with playstyle = people can't stand at the spawn and have a 5 minute slap-fight because they actually have incentive to win?
I don't see the problem.
Incidentally, you don't have to join a clan to get clan balanced. Find a clan you enjoy playing with and just start using their banner symbol. Lots of people do this.
If I'm not mistaken, there's a Euro server with clan balance turned off but nobody plays there. Most people apparently prefer it on.
