As far as gacha are concerned I think so. The story and events are good if you like cute girls and anime cliches. You barely need to engage with the gacha side at all to enjoy the the story as most of the combat sections use preset teams and seemed to be un-losable.
If the chibi autobattler doesn't interest you then the only thing you miss out on by not rolling for specific girls is their relationship and valentine event scenes, which you could watch on Youtube anyway.
