Green Mage is basically what conjurer is to some extent I suppose with the focus on natural elements, so maybe it wouldn't be such one.

Gladiators use Daggers so maybe Gladiator > Dancer that would be funny to see Prance in your heavy armour PRANCE

I think Chemist is what Alchemist is, so may not get that. As well the Thief/Dancer thing works, but then I wonder where Ninja will go, I really want to play Ninja.
