I liked the idea a while back where new clans sort of piggyback on current clans. You can only unlock this clan say if you have all the commons of the certain clan.
Also I like the idea of ur2 as fr was a let down for me. I love the idea of crs leaving to go to that city and that you can only get to that city if you are a certain level

I've always wanted a clan like this because I like cars:

The clan's name will be Speed. The theme will be import tuners and street racing. Their bonus will be protect attack, meaning that -X attack abilities and bonuses will have no effect on them.

What do you think of this idea?

I never thought of a theme like that, different racers and all that wanted by Sentinel and all that. And one with an ability with 8/5 stats at 4 stars with an ability of Protection: Power and Damage.
