We looked at the alternative base layout to help protect it, but that was not deemed viable for Relic to implement, and we looked at giving the ambu a lock down mode for main base sectors so it could have increased durability only there, but couldn't find a simple way to do so.
This is very frustrating to see the USF base layout cannot be updated because that will solve the problem in most 1 v 1 and 2 v 2 maps. Any other changes to the ambulance itself will have high impact on 3 v 3 and 4 v 4 game play.
