Fate/Grand Order

I also plan to grind the current roulette, but not so much for the figurines (I always have enough of them, probably because I play with a small number of units), but rather for the class stones and the specific resource (Hero's Proof) that I really need right now. In general, if you maintain interest in grinding and leveling everything and don't burn out after months or years, that's great. Many people like to criticize gacha games for various reasons, but I think it's an excellent hobby, and this monetization method is quite fair for a long-running project with regular updates.

Regarding the Heroes of Might and Magic units, I also didn't really want to start with them in FGO, but in the end, I couldn't continue to ignore Tomoe. And then, over time, it turned out that there were many more characters that I found interesting than I thought before.
