I'm not experienced with D&D but I've read somewhere that prone glads don't activate any skill so imo a prone war won't activate DFA, CD and especially the invaluable NSD so D&D seems good to me; not sure for the last tier skill but anyways; given that there're skills like Barreling Attack, Sweep, Signature move etc bent on knocking someone down.
But if D&D still sounds mediocre, what if its position were swapped with NSD?
