I just played it in an impromptu test. It's really fun, but it lacks signage. I believe their was someone complaining of getting lost like 3 out of the 5 rounds we played.
The First point blue has to capture is very small and high up. Either move it too the room under and make it easier to defend OR keep it where it is and make it easier to defend.
The 2nd point blue had to capture was difficult to push through (maybe it was because my heavy was being dumb, I was medic). There was a sight line from the 2nd CP to the outlet hallways.
The gameplay it self was solid for a medic. Oh and a side note, the server was filled (32).
Hope this helps!
