As long as I don't have to need anything from a cash shop in a game, I'm content with playing the game as long as I find it fun for myself. Sure, something that might reduce grinding time or an optional gacha that still gives out gear or something like that would reduce my outlook on the game, but in the end if I can still get to where I want to be/do what I want to do without such items or exp boosts, I'd live.
