If no battle goes beyond 4 v 4 and whoever makes events involving non-battling characters is smart, you should always be able to include this unit somewhere on the map.
I assume it has Speed 2 Move 0 PA 0 C-Ev 100 HP 999 Always: Don't Move Always: Wall etc, right?
If so, this is fine with me, as I said before. The skills that heal MP while doing other things (Chakra) should remain untouched, only removing the skills that purely heal MP and aren't Move-MP UP.
I do like this if only for the fact it makes the AI less stupid in longer fights, though.
It also makes IA more unique in how its battle mechanics work, which is a plus.
