In all honesty. This mechanic is absolutely atrocious. Nearly every hero has it and it results in endless attack spam. What happened to the days when you could defend properly? Because they can do it till they nearly run out of stamina, defend against what you can dish out and start it all over again.
You sit and pray for the one move that you can parry effectively, otherwise they hyper armour through anything you throw at them, resulting in a lot more damage you could hope to dish out. Have you ever seen an Orochi try and fight a Highlander as an example? It's like smacking them with a foam noodle. You can hyper armour through Wind gust and Hurricane blast for gods sake.
Fix hyper armour. The amount of characters that just spam attacks because they know they can get away with it is staggering, or allow us to guard break them out of it because god knows people who spam attacks be punished with anything other than a parry. Your options are get screwed, or try and parry them for one or two hits before they startup and hyper armour attack spam again.
Where do you even get these ideas? Wasn't attack spam an issue you wanted to address for over a year? Your solution is to just give people more of an inclination to do it?
Not every hero needs it, Ubi. They really, really don't.
