If I recall correctly they’re intentionally sort of half arsed. Something about the game being focused on first person and matching 3rd and 1st person animations is not worth the effort.
Which is fair enough I think. Other character’s wonky animations are hardly noticable during normal gameplay anyways.
Don’t quote me on that though, it was discussed a long time ago and once again I can’t be bothered digging up the thread because I’m currently on phone (phones suck).
I’ll try to find it when I get back home if no one has found it by then.

Nevermind all that. Found the post
