from when i played it on mapchamp, I really hate some of these sniper sightlines, especially with the lack of flank routes to go fix the sniper problem. Defending first especially, I find myself trying to play heals forward on the tracks and not in the enclosed hallway, and then their team pushes and has a sniper sightline into the hallway and our med is fucked.
There are a few other crazy sightlines too but the BIG PROBLEM I have is that ubered players can't stop the cart. Some real shenanigans right there, ubering in to stop the cart only to find you've actually just fucked yourself, especially on last.
Also put some random objects around the map. i appreciate not wanting to put textures in until the layout is finalized but everything is so bland, callouts are fucking impossible right now
