I like this map, however, I think there are far too many defender spawns on the keep, I have seen times when the attackers got en masse (10+) to the flag and the defenders managed to push them away by mere numbers, people just kept respawning faster than they could be killed (we had a couple of shielders just tanking, a knitting machine, a few maulers, a pretty good team, but I think it could be improved.
The problem is, even with the gate open since minute 1, either attackers did not know it or just because from the gate there is only one option for most players (once they are charging straight ahead they just dont look at other possibilities. A way to fix this could be to rotate the keep 30-60 degrees so that when coming in you haveto choose right or left, that way attackers would naturally split forcing defenders to look at both places better and making it easier to surprise. This way with a couple shielders, pikers and a maul or two (and the greys, HRE usually have a setup of this kind at worst), that entrance is just too defendable, need other easy ways in imo. Maybe even add another one, would be nice to be able to climb from the inside for example.
I must say I love the roof BackDoor, since it is so shootable for the defenders, making it close to suicide to attack there, while the defenders are in position to be hit by not too long melee weapons, great job with that one and the map in general.
