Machinist also does need to reposition for most of their aoes. Spreadshot/shotgun, bioblaster, ricochet and auto crossbow and flamethrower are all cone sprays that work better from just outside of melee. They ate also the most ping dependent out if the 4 listed so with a weak ping, your wildfire is shot in the foot. But it's overall rotation is pretty basic, I'd say summoner is only easier because of the abilities sharing buttons.
