Most other gacha games have little items/cards you get from doing events/missions that you can fuse onto your characters for a boatload of experience. Honestly, I'm surprised this game doesn't have something similar.
Dude I was just thinking that!
We could have Georges (You know, like just a base George that's colored differently to boost element exp?) and like, I don't know how to put it very... Professionally, but like, we
could have an event where you basically fight peacocks at your own level (Or random) because where else do George's come from? Gold Peacocks drop Gold George's, silver Peacocks drop silver George's, etc etc. But the main gist of the idea is, you fight battles at a shot to win an alternative option to fuse for exp.
I feel like we could really benefit using a base item or card to rack up exp as an alt to using prize fights, but at the same time, maybe flesh it out more.
Personally, I think if we could make an affordable and effective item/card for reliable exp, we might be going somewhere...!
