Problem is it's not /martial doing any of that, it's plant/, and any controller or dom can do that with plant.
He uses seeds of confusion on the first group. It's a fire farm, he proceeds to the drop his creepers and gather more groups on top of his group of confused fire farm mobs.
They begin AOEing themselves and all their friends, while he throws down creeepers to take advantage of the corpses. AOE confuses op in farms, not plant/psi.
Only upside I can see is spin kick having a 16 target cap, but's also a untargeted frontal cone (the size of slice, but it literally just does it in a cone in front of you, not on your target) so it's pretty hard to use how he's farming.
