Riggers would be like Death knights in WoW a small army to attack with...
Maybe if they made drones a thing like that you can call your drones (and to a point this works with bound spirits too) every say 3 minutes for x amount of energy, magic, control pool whatever.
Said power would of course refresh regen at a set rate and food, drink whatever would help but the 3 min time limit is firm and the drones, spirits only last for say 1 min to help you out then it shouldn't get to over powered.
