I don't care about customizable stats per se, but what I do care about is having gear with unique effects and traits. Think of like a Rod that does more damage with an elemental spell of that specific elemental day, or a Rod that boosts a certain elemental type attack. How about feet armor that make you run faster, but has low stats? or how about armor that extends the duration of certain abilities or buffs like Blood for Blood or Medica 2? How about having actual elemental weapons and enemies taking more damage to certain types of damage and resisting certain elements?

So many variables that could be added but are not for some reason. Things even casual players could pick up on and enjoy.
