I don't need the "frames" you get from the "Shop" gacha!

I get so disappointed when frames pop up😭. I just keep accumulating the same frames, and I feel like throwing them away... All I want is "Stamina" and "Coins"! But even when I do get Stamina, it's always just "6" or "9"...＿|￣|○💧. I'm still grateful to receive anything, though...
I feel like they could improve their customer service a bit more.
Anyway, frames aren't exciting, and especially Artwork Frames are useless since I don't use them. Frames hold absolutely no appeal.
