"... add a rule that can't attack the same target for next 3 days."
This. I was offline for a week, and one account has been hitting me while I was helpless. I'm not complaining, but it's just enabling predation on folks in the situation I was in to let them just farm accounts like that.
Gangs need to enable folks to pool their armies - that's what gangs actually are and do, for Chrissake! This would enable wee minnows to better remain able to play when big whales are looking for easy pickings. It would make the gang colors just as useful in game as they are in the real world. Maybe a guy feels he could take a random biker in a bar brawl. That same guy will not even try if the biker is wearing a patch - if he's smart.
