Now that you are more than a bunch of friends playing together and claim to be a own faction, I would ask you to find your own bannerslot, and stop using our mighty yellow pidgin of war (or nordic raven with banner pack), so we won't get confused.
Right now teams get balanced by banner, I think you know about that. And if we all use the same banner, the chance that all of 1 faction get in the same team gets smaller and smaller.
