We added your map on our server and I was even able to gather some feedback
1. Last red spawn feels really easy to spawn camp just for single demo. Both exit doors are visible from same spot
2. People complained a bit about platform for BLU before the last point. BLU sniper seems to be safe here and its difficult to get him
There was one more annoying sight line for BLU sniper when BLU tried to cap the last point, but I'm not sure about which flank people spoke about so If I find out I'll let you know
