I get where you're coming from, but at the same time there are some groups (like mentioned in the OP) that have a large following, people that want to rep them (with clan tags and nameplates) and a limit as to how many can actually do that. Realistically will all 250-300 play with eachother? Probably not. But there's still the social aspect of being in a group/clan. There's also the concern that if clan-based rewards/bonuses were introduced, people that were forced to go into separate "subclans" will be encouraged [i]not[/i] to play together, even if they want to.
