I understand that there's an emphasis on parkour elements and free mobility, but I feel as if immersion could have been greatly enhanced if you just added legs like in Mirror's Edge. Sliding looks awkward without them too. FPS's that don't really involve as much freedom of movement like Counterstrike or COD don't have them but that's because you're not really supposed to see them all the time, but when you're mantling/vaulting/sliding stuff, it's just kinda weird imo.
