Sticky cover is fine (I guess), but why the third person switch? With the exception of the dialogue sequences, Deus Ex didn't try to remind you that you're playing a really "badass" character in a video game. You were JC Denton and immersed against your own will (the shooting mechanics notwithstanding).
The reason is that it's kind of disorienting to have a sticky cover system (or melee attacks) in first-person. You want to understand where you are in relation to the environment, and
pulling the camera back provides clear feedback while also improving situational awareness (since you can't really stick your head around a corner in a first-person game without exposing your whole body). I'm not the biggest fan and wish they just had the option to lean around corners, but that doesn't seem possible considering the game's console heritage.
