You... Don't really follow these anime, do you? You'd have to seriously nerf Luffy's power to think that anyone in MHA would stand a chance. It's not to say they're not powerful, but Luffy's entire crew, even the weakest members, are stupid powerful. Luffy is strong enough to level mountains even without his hightened forms. Gear Second alone should have made him stronger and faster than Midorya. To top it off, Luffy is an amazing fighter. He's one of those characters who is an idiot in everything BUT combat, but in actual combat is a top notch genius. Midorya is a good fighter, but has very little actual combat experience. Totally one sided match that only went on as long as it did because you were pretending their powers were even remotely near each other.
All this said, the animation was pretty decent. You should see if Death battle is hiring new animators!
