It brought up a contradiction I never really thought of. You simultaneously have to grind to build up your magic stock while at the same time from a level perspective not needing to grind at all because the enemies grow with you.
It's not really a big deal, especially if you know how to manipulate the system and get card mod early on, but it definitely would have been more cohesive if the enemies didn't level with you. It would make the traditional grinding more worth it.
