How should My Hero Academia end?

I would personally like it to end with the One for All and All for One quirks being destroyed in one final battle. And somehow, since All for One can take away quirks, all the quirks that All for One(or whoever bares All for One if it's inheritable like OFA, likely Shigaraki)has taken get manifested back into their original users. If the theory about All for One stealing Izuku's quirk in this case is true, maybe he can learn his true quirk in the end. Not to mention with All for One and One for All gone from this world, the power gaps in the anime will be more balanced and there would be more competition.
