I am fine with the amount kamihime gives us daily... just the fact that the chances of actually getting something useful out of the stuff they give us is abyssmal.
GBF for example has 'spark' feature which lets you save up for around 6-12 month and then get a guaranteed girl of your choice(+ most likely some neat stuff along with it).. along with events for 'rolling gacha' with increased %/other bonuses which lets you choose when you want to spark.
It also gives out some actually DECENT SSR's for free.
TBH kamihime is actually rather generous on giving us crystals as well(look at how many collab/summer daily/other types of crystals were given out) but the fact that using them is HEAVY rng is discouraging.
You might save up for a year and still get nothing or maybe a duplicate of your only SSR(since I am quite sure it's rigged to give you more duplicates than actual SSR)
