Make third person viewmodel offsets a thing, so a new third person game mode can be better accessible.

This could open a window to a brand new custom game community. Just like Surf, Bhop, or Zombie escape. Right now, the crosshair is glued to your head, and you cant see when your crosshair is directly looking at. Using third-person over the shoulder adds a whole new perspective to the game. Not to be used in competitive, but in fun games where cheats are enabled or used to make these game modes playable, like listed above. Communities could sprout, and make new maps and things to better suit this third person playstyle.
P.S. I just found out, your body tilts in the direction you are moving.
