Except for that stupid physics breaking shield of his, I don't see how Cap A can be considered overpowered. (even if there was a material that universally impervious to damage, it would still react to impact, not just stand in place without at least transferring kinetic energy to the arm holding it.
I love the shield. I believe the reason it does not transfer the kinetic energy, is because it reflects it.
Newtonian law of physics number three. Every action provokes an equal and opposite reaction.
You cannot simply reflect kinetic energy, it can be distorted, warped, transferred, dissipated, etc. but it is impossible to get it to reverse direction, no matter what kind of material you are working with. What you can do is generate an opposing force which causes your moving object to reverse direction, but all you have really accomplished is an energy swap, not a reversal. The object that was hit still has to deal with that same kinetic energy.
Imagine holding up a shield like that, and letting someone hit it with a sledgehammer. Your arm, and through it the rest of your body, still has to deal with exactly the same amount of kinetic energy as if you had tried to block the blow without the shield. The shield just gives you a work advantage that lets you stretch out and soften the impact. Kind of like the tire shocks on a car or bike.
This setup has its limits:
-one, no matter what, a heavy enough blow will send a shock through your arm strong enough to shatter bone, or worse.
-two, the less the shield itself moves, the less the impact of the blow is mitigated. If it doesn't move at all, you almost might as well be blocking it barehanded.
Given the force behind some of the blows Cap A has taken on that shield, the realistic outcomes are not exactly pretty.
Either he successfully braces the shield such that it does not significantly move, just like in the comics/movies, and the resulting kinetic shock turns most of his innards to bone shrapnel filled goop. Or, more likely, he does not, and the shield goes flying, probably crushing him in the process.
