With the exception of a handful of games, we can all agree that JRPGs are really, really bad, right?

How so? Plenty of SMT bosses have strict and punishing patterns. If you look shit up and over prepare of course you can copy a strat and do something and make it look easy. Since jrpg bosses like most single player games are an absolute but require no actual reaction timing.

But when you don't and just play of course you have to manage resources and strategize on a fly.

Nah some. Kingdom Hearts is comically one of the most advanced ones. Tales games Star Ocean games etc are all braindead. Essentially just spamming the most powerful shit you got and spamming items on top well tanking. Only rarely do you avoid a few key attacks.

Sounds like you just like active elements a bit more than number crunching, user.
Maybe SRPGs or action games are more your style.

Personally I love Etrian's combat, it has extremely well-tuned balancing and a ton of possible party combinations.
Stuff like DQ8 and FF (mainline) just seem pathetically easy in comparison, but those games also have their own positives.

Maybe "Tales of" would be a good series for you, user.
Action-based gameplay, positioning matters, still RPG/levelup mechanics but lacking in customization.
