After playing this quite a few times lately on hslan, I see that this map just wont work.
Things might go well and map plays out as it was intended, but more often, germans capture fountain flag and start siege on allied base. Map is so narrow beween fountain flag and allied base, that germans can easily defend there for whole round. Could make things easier, if OOB areas would be opened north and south from allied base. More room to sneak trough
