I noticed that the first person model (of ourselves) is a little bit bugged, when we watch our feet and we run textures are superimposing and it's not really beautiful :'p.
Also, that makes me think about something always annoyed me in Bf since bf3 : we ALWAYS have the same first person 3d model, it's a big mistake to me because it doesn't make sense knowing that every class have their own "exterior" 3d model
---> So it should be cool to "fix" this with mods, and maybe have differents models for the same class !
