Eh, stamina refills can have questionable value themselves. Between my level being sufficiently high (yay being in the needing near 20 hours to refill stamina club) and my normal schedule, stamina refills have zero value to me most of the time. I just need to keep a reserve in case of trips.
Raid boss events can be manic though.

11-rolls themselves are a gamble (and I've had horrendous luck with them). But there's really little else to even spend flower gems on for some free players. What's there to get/do with them? Push your storage slots from X00 to X50? Great, that's 10 gems. AKA 1 week worth of gems (8 from a half of the main event, 1 from a half of a reprint, and 1 from every 5th day). One weak later? Push your storage slots from X50 to the next multiple of 100? Eventually you either hit 'enough' or 'current maximum the game allows'.
And it's been long enough since there were stuff to buy with gems (like the rainbow dressblooms for 50 gems each) or did the 'do a 50 gem 11-pull and get a 5* gacha ticket' offer that it's safe to assume they'll never come back. What else is there to even do with gems? It's basically why this week I shrugged and threw 100 out of my ~220 gems to try (and fail) getting the Lycoris variant.

If it makes you feel better, I spent $40 for the one-use gacha under the erroneous assumption that I'd be able to get Shrine Maiden Lycoris with it!

It sort of worked out for me anyway due to some dumb luck with the gacha rolls, and I probably would've done it anyway even if I knew the Lycoris form I wanted was off the table (her new design is so much better than her old one!), but I miscalculated on that one.

Stamina boosting was of great use to me in the last event, if only because I can't imagine flipping all those cards for the stuff I wanted without it. Then again, I'm only LV 58 right now.

^Art direction.

I agree with this certainly. 2-3 girls are pretty much the same models with swapped hair, although there have been some redos with girls like Di Yu. The whole Waifu things is why I like having different girls in a squad instead of multiple versions of say Peach due to my sad obsession with roleplaying *sob sob*
