Well done IMHO.
Now you can roll right out without any tight turns, cover the map room, up a Wirb to shoot the ackers from inside the walls, or peak out from one of the walls if campers are trying to suppress base defenders. Removing the back door is also a great idea. We won't see any snipers with a perked ride high on hill killing spawners anymore.
There are already allot more tank battles on a v base than we ever saw in AH2 because the terrain allows allot of gv's to hide on base. The walls now provide much needed cover when defending a base.
