What is the point of TP by now?

It just sounds silly for any sort of physical ability to cost magic points.

Could easily see them justify it by doing this...
"To execute skills you must draw upon your personal aether, represented by MP."

But it still would be silly unless they are tied to more specific sets of moves. Normal punches, sword swings or pew pews shouldn't cost aether. Otherwise anything that is exerting, even walking or running like we do as default, should technically cost aether too. Personally I think this would work better if we had the XI system or building up TP to use for specific moves. Would certainly make combat more interesting and tactical.
