All the problems this map has, it inherited from the original. They just become more obvious with the changed gameplay mechanics in RO2.
The problem is simply that the Axis hold all the flanks, and the Allies cannot flank at all. The right edge of the map, and lack of cover that side, prevents any flanking on the right. The left flank the Allies always have to worry about being flanked by the Axis. Hell once the doors are blown, the Axis can push forward to a decent defensive position to fire directly at Allies leaving their spawn.
Put simply unless well timed with C already capped, blowing the doors into the halls actually helps the Germans more than the Allies. It's never a good sign when blowing up an objective helps the defender.
There needs to be some major reworking of the map to make it workable in RO2.
