I don't see the need. Grinding is already fairly boring, and being OP is (sometimes) boring, so for the people who don't agree with my opinion on those, I'll just let them grind and get OP. Mind, skills on level up that can break flow (such as Unlock in DQ2) shouldn't be tied to levels anyway. What, like FF1? For being such old games, DQ and FF actually messed around with some assumptions of their time.
