I would have voted for the Mystic if the option was there :<
Seeing how it's not, I would say I had more fun on my Venomancer ^^ Between turning your targets into puffbirds, taking their chi, purging, amplifying, AOE seal/HF effect, a chance for 0 pdef, a chance to reduce their physical and or magical resistance by 100%...there's just so much =P Though, I'm only referring to a demon venomancer, but it's essentially the same either way.
