Well as 4 of my guys are 36/38 I think Ill fire spec for now to get blast wave.

None of the 3 51 points mage talents seems to be all that so not sure what Ill do after blast wave.... Living bomb is good but as you point out its usless if the target dies to fast.

Ya Ice Barrier protects for 3300 damage at best. Far from the pal immunity bubble ...
