I dont think dimensions need to be changed, it takes teamwork if you are nuking, fail to do that results in failure.

The map is a challenge and is new to PUG, I think you need to give it a good 5-10 more PUG matches on it before changing anything (apart from the mover lift, have it slightly above the floor like a curb because it is causing bsp flicker if level with the floor and also make it level with the top)

maybe the only other thing is cut out an area above the lift for lift jump onto the ramp, increase the move time slightly so you make the lift jump.

apart from that, I personally cant see any other faults RE nuke room size etc.

dont make easier trans entrance, that will just give me more RU, 100-2400RU in six seconds
