I'm not against paying something for these games, truth I've spent way too much money on Pay2Win games in the past, (Forge of Empires, Wartune, PeroPero, Hitsuji, Gems of War). You shouldn't feel shame when thinking of games you've played.

But in this case, and especially the Nutaku games, its all gambling. Spend $50 for a chance, a really low chance, at getting something good. IF you've seen some of the videos posted where someone spends $200, spins the 50 Flower Gem gacha 6 times, and no 6 star girls. Thats harsh. But thats a ridiculous system. You litterally have better odds of betting that $200 on anything in a Casino, and the prize would be a hell of a lot better than an imaginary item on screen. Spend $200 on roulette, and your odds are 1 out 38, if you bet on a single number. The prize would be 35 to 1, which is Seven Thousand Dollars.

What happens in Flower Knight girl? Spend $200, get 6 chances at 0.5%, and your reward is a rare digital item.
Doesn't seem nearly worth it.

But aside from that, and the harsh lessons I've learned from these gambling games, does anyone need these girls? I dont have any 6 star girls, and my teams can beat every level thats come up so far. Sometimes they can be a bit challenging, and I have to spend some time arranging the teams, upgrading the girls, equipping or upgrading items. But in the end, I've ended up beating all of the boards. Most of the time, its with relative ease. Has anyone been in a position where they cant beat the board, and a single 6 star girl would turn the tide? Change things enough that it would be worth spending $50 to get her?

Sure it would be nice to have one, but is that the only incentive? Because it would be nice to have one?
$50 is too much. When its get offered at a cheaper price, they'll probably get a sucker like me to buy it.
But not this time around.
