P5R but Every Persona is Weak to Everything

In Persona the 1 more mechanic is usually abused by the player to wipe entire battles with ease, but the enemies rarely benefit from this. So I decided to mod my game to make every Persona (the enemies are unaffected) weak to every element. Giving them not only consistent 1 more's, but also increased damage. That combined quite nicely with this game's merciless difficulty, that increases both player and enemy weakness damage taken to 3x. Overall, this made for a fun challenge. That added just enough difficulty to create an interesting but fair difficulty increase, for a generally speaking easy game.
