By virtue of potentially three against one, I'd rather thank.

I spoke with Ryo in PM.  Ebon's power has been nerfed to the degree that his telekinesis doesn't work on living things unless they're completely vulnerable, and his telepathy doesn't work unless he's both focused and his opponent's mind isn't excited by battle.  When fighting, he essentially has his shield and his drones, and little else.  This should not make him overpowered.
