That's the problem with all of them, still some people love shaft. 9_6 There is a fact - no matter how stupid the idea, there will be people following it. In this case - buy / usage statistics will show the game makers how much people really appreciate the weapon.

Disappointed and want refund. Shaft m0, m1 is trash because: - can't move when shooting; - shaking aim at top load; - to cancel shot need to wait until shaft "unloads"; - player is a sitting duck with this weapon. Enemy can just wait in cover until he shoots, then kill him afterwards; - pretty much useless against close range attacks. Maybe m3 is decently good, but was not stupid enough to pay the price to maybe get disappointed again.
