Why did you drop your previous gacha game(s)?

Feeling nostalgic after reading Arknight story spoiler in another post.

Here's mine:

GFL (JP) - Dropped soon after introduction of fairy system. The combat system went from chill team formation auto-battle, to requiring precise movements to dodge enemy hits or risk game reset. The fairy system adds another layer of complexity and grinding to the combat at which point I just nope out of it.

AK (JP) - Dropped after finishing episode 8 (final Lungmen arc / Talulah backstory). Too wordy; I still have PTSD whenever I remember Talulah eating bread at the old woman's house. Despite being way wordier, the end of the arc doesn't give that satisfactory oomph ala Blue Archive final volume either.

Umamusume (JP) - Dropped around first anni. Every run taking up 30 minutes to an hour is way too much. The side stories are hit-or-miss as well.
