i think there should be one and it could enter for a hole new way of designing levels with traps that we can dodge or have to jump over. like have a barrel trap that rolls barrels down a path and u have to jump over them to get past. or have a dodge button that makes u strafe left or right or even do a roll in the direction.
Knights are solid metal and therefore incapable of jumping or getting up by themselves!
As for a dodge button... we already have strafing as an option, and a high-speed dodge would probably be a poor idea, since people would spam it as a makeshift Striker boost.
