yeah, thats quite nice trick
I especially like the idea of fiery tank, all magical damage, but with shield giving him great survivability->
Using phoenix dive to jump in the middle of fight, using supernova, ignition, fireball into impalement, fossil strike or contagion for mass aoe destruction sounds like shitton of fun... Probably best with red prince++elemental affinity+demon talent
Quite possibly very good with necromancy, giving you some physical damage when needed and sustaining your health should you take too much damage
Back to the question - lvl10, mages still wrecks everything while having great utility. Their single target damage of course cant compare to rogue/ranger, but their overall damage is through the roof... I do advise to have two mages tho, and both should have atleast 2-3 damage types, so you can avoid being useless against immune enemies
