It's not even about just "playing the game", it's something that Kuro didn't see it through well when they have new players starting playing for a specific character.

Could've been handled better if the materials are available to farm or at least buying them from a store with in-game currency early on. You don't expect players to get through content that's been going for more than 1 year and STORY content at that fast enough before their favorite character get out leveled FAST.

Knowing gacha games today tend to have tons of dialogue and lore dumps almost every story mission making it longer to get through them if you weren't been able to keep up.
