Omg... are you serious? Are you nerfing First Person View? Looking at your post it means you can only 'run' ( AKA move faster ) in third person view.
In the beginning especially it is annoying.
1. You jump fewer distance in first person.
2. In third person it's hard to jump.
3. Annoying view if
3a. Third person goes trough walls ( Probally not )
3b. The camera goes more toward your character once you hit a wall ( Probally is )
Both are just plain annoying.
Not fighting in third person is fine for me, i don't really need those animations. Maybe in v2 if that one will come ;).
