Played this at gameday. Initial reaction: Way too big
Here's some problems:
-Way too open. When going down the ramps, the sightline is huge and snipers were at an overall advantage. Half my team was snipers.
-No elevators. Engy's could build on them, they were too slow, and they are rarely used in TF2
-Coming out of spawn, you are immediately thrown into intense action if you go into the building. I think you should give some buffer room between the spawns and the actual cap point
-Some areas of the map, especially below the ramps, were almost pitch black.
The map needs some work, but the main problem is scaling issues.
