That presentation aside : the same mechanics "really are" I think at D&D's abstraction level often just as appropriate for martial effects once you get past the meta elements.
Superiority Dice? reads like a meta mechanic to me .... it could have been ki acknowledging the relationship in monks deep effort (or even called grit if you want something different or perhaps muscle fatigue or heck give it a mental cast as Battle focus ).
Oh I know tell me to make up what that ablative ability is to me, please do.
I think it is far less of a problem than people make it to be.
