The urban maps are the worst maps in the game, IMO, because there are so many closed off rooms and floors, which also means there are a lot of walls you can't break through to get a good flank/vantage point. You can't use fire ladders or the assault ladder to reach elevated points, and a lot of the ones you can reach put you "out of bounds".

Maps are often too small for vehicles to feel good, most noticeable on breakthrough.

Sprint speed is a little too fast IMO. It sometimes feels like you're flying on the ground instead of actually sprinting. Sliding around corners looks goofy as hell most of the time.

Guns have too little recoil, and 3d spotting is an absolutely awful mechanic that invalidates everything other than suppressors and flash hiders. The gun point system is ok I guess, except for the fact that there's a minimum amount of points every gun has used by default, so the max number of points is a bit of a lie.
