Extremely p2w game (you literally pay for more attempts, resources, etc.) anybody who says otherwise is delusional. Ridiculously heavy grind and very bad rates. I own very few URs and yet somehow I always pull a dupe UR when it's a non guaranteed featured UR. Something's fishy when I only own 2 URs in the entire banner pool yet somehow always manage to get a dupe. That being said at the very least they're not too stingy with currency, but it really doesn't matter when the rates are bad.
