@lobo:
you cant compare a pushmap (siege of tobruk), with enemy bases in direct shooting line and a very limited angle of possible enemy attacks, with a map like crete, where the bases can be taken in no particular order, with no possiblity to "boforsrape" another spawnpoint due to leveldesign.
so besides using the bofors for the obvious (aa-duty), allies have the chance to include those very effective weapons in their ground defense/attack plans, while axis dont have that advantage, even when they manage to capture the base. add the allied tanks to that situation, and you get what we have now, an allied superiority resulting in an average 6-7 vs 1 win count for a battle, which has historically been won by the axis.
seriously, unlock that bofors, and the map will be balanced! that step will in no way reduce the level of allied airdefense, it will only even the chances of the groundtroops battling each other.
