Oh, I don't know about you, but one of my characters has both potion lores.
So, I set him as such.

1: Ally: HP<50% Potion
2: Ally: HP<50% Cure

Since potions heal like 120 with (SPOILER)Basch, and they are so much faster than cure, I use them first.

Of course, the key to this is to have the other charcters as such:

ALLY: HP<80% Protect
ALLY: HP<30% Cure

That way, I don't waste my potions, and my allies are amply protected.
