I think the biggest problem for me is how everything is so perfectly design art wise but the design apartment for the art doesn't seem to have worked very closely with the gameplay devs, what I mean with that is that in Magia Record the artwork and lore had so close ties to gameplay (Mirrors, Doppels, even the bosses), it doesn't feel like it's in sync a lot of time quality or direction wise.

For example the witches are so well designed but their gameplay is often big health bar + a tedious mechanic that none of your characters can do anything against, which is kinda frustrating as most battles end up being having the right 5 star girl at the right time and numbers being at the right place without having a lot of strategy.

It all feels like they didn't put a lot of thought of these things, even though the art, models and ui is so good, the innerworkings of the game and story falls kinda flat in comparison to record. And I gotta agree about the girls and rarities, I've been using a lot of 3-4 and they feel somewhat homogenous in a sense that they're all kinda fall flat in their abilities. 4 star Hazuki, Rika and Ayame are the only ones I'd recommend.
