Celtic Heroes

Hey all, I am making a mage to be my new tank (getting 2 more devices soon), and am wondering whether I should go fire or ice?

Fire Skills that I have (tell me if I am missing any):
-Attune
-Bolt
-Lure
-Cloak
-Storm
-Incinerate

Ice Skills that I have (tell me if I am missing any):
-Attune
-Shard
-Sheild
-Sacr
-Blast
-Freeze
-DOT Ice Spell (Forgot name, looks kind of like ward of ice symbol)
-Lure
-EBoost

*Also have all lures*

Using these skills and a pro/con list, what should I go with to level? I would like to choose one or the other (i have royal/grand rings for most of the skills).... And I can purchase blades/axes for h2h.

Thanks,
Regenleif
