Suggestions for shields in combat

I think shields could use alternative attack, namely a shield bash. I think when guarding with a shield we should be able to push back enemies with a shield bash similar to the kick we get when using only a one handed without a shield or a two handed weapon albeit with a slight damage buff depending on the type of shield, also possibly have the shield bash have a chance to knockdown npc’s in combat similar to certain weapon combos.

I think there is a shield bash. Don’t quite remember how it’s implemented. A certain weapon combo with a certain skill perk? Not sure but I’m almost positive there is a shield attack. Alas I am not 100% so this could all be for nothing. Lolz
