xbox/microsoft doesn't make fight sticks, niether does PS3/sony, tell the legion of gamers that use them that there wins are no good.
Hitbox is another controller, somepeople can use them, some people can. Some people can afford them, some people can't.
This is competitive gaming if it gave that much of an advantage, everyone would be using them,
as it is in MK
I would say 70%Pad / 29%Fightstick /1%Hitbox -
Nothing that can be done on hit box can't be done on Pad or Stick, they will not be banned.
