The only two jobs I know that is not truly penalized for movement is summoner and ninja. I believe fights are not suppose to be centered around all the DD's having 100% upkeep time on dps. That was why the bard was changed makes believe that. And bard is heads over heels in a better spot then a machinist who has to manage procs, mini cooldowns and a stupid charge up mechanic that requires most burst in the window frame to maximize damage along with proper turret placement for mediocre dps on par with a paladin and tanks. Be glad you are not a mechanist.
