If an enemie has only one kind of armor, he is dead meat anyway. You don't need to deal damage, to keep him in deathlock. Same goes for every enemie who got ripped of his armor, one of the reason why physical is so strong. Knock down effects are the easiest way to keep enemies down, after they lost all their armor. Also it is much easier to increase your physical damage output than your magical. Magic feels very weak early in the game, even more if you go hydro/aero which is a cc heavy combo. Though no really point in repeating even more of all the issues in the armor system, that got repeated over and over again.
In the end except from some special fights, most of the fights just felt the same, also more like playing puzzle game and less like having a fight.
