Why does JRPG combat need to be "fixed"?
There's nothing wrong with turn based combat if the encounters are designed in a way that you need to adapt to enemies and can't win them all with the same strategy.
I played E33, SMTV and Trails in the Sky this year and E33 was my least favorite combat of these because of the active elements that completely messed up the balance of the game.
I guess some fun gimmick is needed tho or otherwise you get Dragon Quest combat which is so dry it puts me to sleep.
