I pulled out my old PS emulation of Final Fantasy tactics to show it to a friend the other day, and suddenly had an idea for a non-magic based healer. Basicy....the Chemist.

I don't even think you would need to break the healing mold to much. simply have him/her throw potions or throw up a potion that explodes to do an AoE healing. I realize that the 1-50 levels for healers are pretty formulaic. But the real treat might be it's mechanics.

So for mechanics I was thinking basically have you mixing effects. So as a basic example if you throw out a basic HoT potion/spell if you throw out a haste potion you get a very strong HoT that ticks twice as fast. Or using a hast and damage potion makes basic attacks do damage to all enemies in range and in front of the target.

In short, make it kind of like the ninja's ninjitsu where certain potion combos give certain buffs and effects. I personally would love a healer that had stronger support mechanics, and I love the AST.
