The movement around the first turret is extremely clunky. You get caught up on the turret itself and objects around the turret far too often. Fighting around that area is frustrating at best and could use some optimization to make movements in that area more fluid.

on first objective the movement issue really comes into play when you are jumping through the hole in the wall. while it is frustrating i dont think you are meant to jump through the hole (there might be a mg in the way).
For the area around the mg i personally like that most of the combat is centered around the windows and holes in the wall. both attack and defense have sightlines into the building through the windows that can hit the normal cover. while the holes give people cover, people will usually use them as cover so they can be predictable. the holes also make using grenades in the room slightly harder to use but more effective.
this area tends to come down to holding the right angles.
