I'm a little disappointed you don't actually get a free item or a free spin. I had thought about getting premium but probably won't now if I can't use the item reward. At least I can save money on it.

Gambling/real-currency gacha is something I don't spend on because I'm very careful with money and always do the math to find out the realistic probabilities of everything I pay for so that I know exactly what I'm buying and what the best alternative is (I hope others learn to do the same but I know that not everyone took a stats class), so I'd never get to use the premium bonus because the odds of the gacha are so bad compared to the bundle price.

...It's also illegal in my partner's country, among a number of others, so making rewards contingent on loot crate mechanics locks a lot of people out of supporting it based on region :c
