If you dropped the Incarnation of Sigmar and the Hammer, Karl Franz will drop way down in points, and he won't be OTT. They could probably make his rules official at this point.
And I do agree queek...Thyrus Gormann is way too good (D6+1 Fireball, 2D6+2 Firey Blast, D6+1 Conflageration, + to spell range). He needs some toning down.
