I play a ton of gacha games, and mostly ignore the gacha pulls once I have a main team picked out. I don't see any point or reason to level up additional parties, or characters, and the idea of pulling for more characters that would start at level 1 is pointless for how I play.
I'll claim the free pulls just to do it, as part of dailies, but beyond that I don't really see the point.
I've also never spent money on any of em, despite playing daily for 5-7+ years.
That said, I think gacha pulls for weapons or like stat buffs are insane and the stupidest way to dilute what people are there for (Characters/costumes). If a game has that kind of gacha, I'll bounce, because it implies an insane grind
