Should there be a slight inertia implemented to body movement?

[Jonathan_Archer_nx01]

I would say yes as this could remove zig-zag moving and other thinks we are not able to do in real life. I know BF2 engine can handle this as vehicles already do it.

the main inertia problem is the ability to 360 on your stomach with your aim completely unaffected - aim at the head and suddenly your bullet is hitting the hostile's boots
