Didn't know where to report about playtesting, but here are a few "problems" I think should be fixed:
-Gate on A site doesn't close.
-Maybe add some kind of sign to the floor at A gate, to indicate when the gate is going to open, as it's a huge tell that you're going to attack.
-On A ramp there is a boost spot on the right where you can get boosted to the site, CTs can easily gun you down from the A site barred window and therefore this boost spot is useless. The window could be moved just slightly to the left to block vision.
-I think it should be easier to throw grenades to the A site ladder room. Maybe raise the wall on the farther side of it so you can bounce nades off that.
-The wall bangable slice on mid CT window should be just a little bit wider so you could at least hide in there.
-I tried to jump from upper mid stage to the fence and to the mid CT window from there, but I got blocked by the sky. Please fix!
-On B site T window looks like you can just walk over it to the site but you can't. Add clip brush.
-On B site "under the balcony" should not be visible from the T side window. Maybe move boxes little bit to the right.

Otherwise very awesome and tactical map! Keep it up :)
