Suggestion

The whole 'must get new satellite code' after fortress has done nothing but complicate and slow down the game. It was a failed attempt to stop center control and hasn't worked.. why not just remove it again back to how it was before. There are many people like myself who like to hang around and actually help others get their fortress badges, having to either quit alliance before the fortress falls or keep bases in the satellite code zone to get new codes is nothing but a major inconvenience to players. Same goes for the 'fortress attacks back' option.
Trying to stop or handicap players from multi fortress hits will only cause them to want to control the center and keep anybody out.
