Being able to re-bind the camera to Q and E (for me) would be wonderful.

The "ship" map is the one with the door ways that are obscured.  I think colored silhouettes would be good.  If it has a red dot on the mini map it should have a silhouette you can see through a wall? 

You might want to consider also that the intention of the map is to obscure a bit.  Image the Adrift Ship map with little lighting.  Just emergency lights and your torch/head lamp.  >8)  Oh, idea...(heads to suggestion forum)

Camera needs a complete rework. It would suffice if it was a purely melee slasher, but we have ranged weapons and most of time you can't see well even after rotating it to convenient angle. Just take a look at other games: draw and outline for every enemy that is obscured by terrain from player, but in LOS of character. Ignore walls and columns above certain level or too close to camera: why the heck my gun tries to shoot at the ceiling when I am in fact targeting that fellow in next room? Why most objects properly become transparent (although too late) when they obscure view, but some doors and elements won't no matter what?

Agreed. It would also be nice if the camera floated and followed you to point in the up position. I find myself constantly rotating the camera so the enemies are in front of me.

Agree
