Anyone notice that Storm lord does strangely less damage than Fire Dragon? Just a though 8)
Fire Dragon is a damage over time. Therefore, it can't sufficiently benefit from traps. Storm Lord, on the other hand, deals all its damage up front and when combined with windstorm (the only spell I can think of that puts traps on all enemies in one turn) can therefore deal much more damage, with the added benefit of a stun at the end. Incidentally, I think its the stun that reduces the base damage.
fire dragon is not over powered because storm lord does around 700 with a stun dragon does a total of around 900 with no sstun so that is what a 200 difference it not ever powered at all it just uses fire ability to hit iver rounds and storm just hits big and stun them deal with it
