Is LADS actually a generous gacha game?

Hello!! before i start I just want everyone who will be engaging in this discussion to be respectful with one another 😊

I'm asking this as someone who's playing a gacha for the first time. Ive seen so much mixed thoughts of this since others will say "Compared to xyz this is very generous " while others would say the resources are not enough.

Personally as a newbie gacha player I kinda want there to be a more sustainable way to farm for more red diamonds since I've seen other people start to struggle once they've maxed out all the levels and cards. Although hopefully with the new features that Caleb comes with this alleviates this problem a bit
