The novelty wins you out at first; they show you the prologue scene (and it's good), the RPG battles are easy, your first SSR pull is guaranteed at 20 units.
At world 4, the battles' difficulty takes a huge increase, with them often doubling or even tripling your team's power, and the only way to win is to increase your units' level, for which you have to keep playing because they're limited to your OWN level. Plus everything costs gold, and it's scarce. And your units' scenes actually take a lot of both time and resources to unlock.
A positive would be that the game doesn't actually take much of your time unless you want to actively maximize your resources and grind... like every gacha.
My point is, the gameplay loop as its core it's not exactly the best after a while, and if you're like me and the novelty of the characters wore out, then just drop it.
And you're not playing this for the story either.
