I was thinking, for the Battle of Hoth after the Imperials have destroyed the Shield Generator, that the battle completely shifts towards fighting in echo base. This could be done by using a method similar to that found in the Push Map mode found in the FH series of games. where once an outpost is taken the defender can no longer retake it. This way when the shield generator is destroyed the Rebels are actually forced to retreat and cannot retake any outposts other than those found in Echo Base. This would promote an infantry battle and make the fight for Echo Base very difficult for the Imperial Team and give the Rebels more of a reason to work together and hold on to their cps. It would also prevent any imperials from taking Echo Base prematurely.
