ive tested TB yesterday, both ice mode and fire mode

ice: the shatter mechanoc  if fun, and a nice way to do damage

but ice mage have a problem, early game, he get destroyed too easely, and his dmg is way too low early game, but i think hes pretty decent end game

he just need to be stronger early, and i also believe deep freeze should still slow the target like before again, because permafrost aura is not effective

and the castign time of ice nova is a bit too long for just gettin a 1 sec stun at the first level

but overall nice work

Fire: still powerfull , and nice, but seriously, you need to remove rign of fire , and give him a new spell, ring of fire is not worth it, maybe have an imolation spell instead, that will do damage to nerby  unit close to the TB, when its active, its would permanently drain mana

or if you keep ring of fire, make it usefull, end game, the time you take to cast it, you do way more damage over time with your normal atack, and people easely get away, its only usefull vs mobs

also, the fire and ice talent is interesting, to get deepfrezze to max to boost fireball, or deepfrezze shatter, can be worth to get for either fire or ice mage

anyway... good job in general, but tweakign is needed, especially ice mage early game
