Base wont be removed. I am the only person able to remove it, and I can assure you it will stay!!!!!!!! If you wish to improve it, make a list of changes to mercs, bases, canister drops, etc and I will try to complete it when I have free time. Or, if you have any other suggestions. I won't be able to give you the gun for it though, it would have to be out of sheer love of the game mode for you to help.
