Dev's should look into this.
Maybe put a timer on each piece of equipment you want to keep and if you want to immediately jump back in battle you have to destroy the gear you are wearing?
Or make so that if a blue get killed twice in 20 minutes drop his gear?
Or whatever. Right now, red clans wont stand a chance against blue clans in wars. Lemmings are not good for this kind of games.
Anyway it's still a beta and I am sure they will come up with something. Probably protections against red and viable pk play style are things that will be balanced along the way.
