this sounds like a really bad idea. instead of being able to retreat and end the battle you will be forced to keep running and elude until the game timer is up. this will cause the game that could have ended, to continue on. make the retreat timer 15 seconds to match the out of bounds timer, and you will not have to chase all the way to the north corner border.
also, there in no reason for players to be forced to let you sink thier ship and incur the repair bill, how ever much it is. that is the reason for this whole "half thought out" suggestion. you believe you are entilted to the little extra attack..........
how is the last ship to leave the battlefield betraying the team? what team are they betraying?
i still believe the best suggestion would be....... less suggestions.
stop watering down the suggestions forums with nonsence.
