It's a trap to think like that. I don't know if you're new to gacha or you just drank the kool-aid, but decide for yourself what $50 is worth. For the cost of maybe getting one character in this game, you could buy a fully featured AAA game like Cyberpunk 2077 or whatever else you fancy.
Yes, this game gives you a lot for free. That doesn't mean the monetization is anywhere close to reasonable by any metric outside of gacha games, and even amongst gacha games this has some of the worst rates for the price. 0.6% is literally the lowest I've seen for max rarity in any gacha. And to actually max a character you need additional copies.
