@SalutexMO I don't understand why you've ignored almost every single productive post and only look at the ones being toxic to you. Do you enjoy hurting yourself? You don't even bother responding to something that addresses your topic.
It is okay to get hit with Hero, just because the mechanic penalises you for it doesn't make it bad design because it gives you plenty of methods to regain yourself. You have Hero Counter, Hero Refresh and Hero Will, all to make sure that when you're using this risky style you have ways of regaining your damage boost.
Even if you did have a complaint with the class, it would be a numbers issue, not a design issue (a numbers issue which SEGA has already seen fit to address). Please stop using terms you don't understand.
Last thing to note is that the way you perceive playing the class is, is a you problem. No one else is holding themselves to the standards you're setting here. If that's how you want to perceive optimal Hero play, then okay, but imposing your own standards onto something and calling it bad design is just straight up wrong.
