I agree.
I'm not liking the prices at all. Especially for the Gacha, 5$ per roll is just ridiculous when you'll more than likely end up with garbage unless you plan on spending a lot of money on it.
Another thing I really don't like is how the costumes are currently only in the Gacha. Though that could possibly change later, I really think there should be a set of costumes available from the regular store (At a reasonable price now of course, c'mon, I doubt anyone wants to spend like 40$ for a costume), and then some rarer costumes in the gacha for people who want to try their luck with being more unique.
And then the Premium boosts. Putting it straight, none of them are even remotely worth considering. They do however have the right idea with the bonus free items/rolls and stuff when you spend larger amounts, thats always nice to see, especially with the Gacha, if it weren't for it's ridiculously high price that is.
