I dont mind it. There's the price of the bundle, which is fixed and totally comparable to the bundles they've been selling all along, and then for the same price you get 10 random items. It doesnt seem like a bad deal to me. In fact I picture myself spinning for 10 every time instead of getting a guaranteed 6.

I say this recognizing that I go not understand the legailty of gachas for real life currency.

HOWEVER, I do think that it would be better to market this site to 18+ or at the very least gate purchases to the 18+ members. :)
