I didn't enjoy 15 because it sat in a weird middle ground where it kind of wanted to be action but the mechanics didn't justify it. If you just lean into ARPG, that's a space that could use more complex options.
I get being disappointed that there aren't really AAA JRPG options left, but the tech is to the point where it doesn't take a AAA budget to make them any more. Just like platformers and metroidvanias are largely dominated by small studios that are as good or better than anything AAA left, JRPGs have options and can be made by small teams reasonably comfortably now. I like the genre but I think that path is perfectly fine. It also lowers the price point allowing you to explore more options.
