The one point in Arcane Stability would serve more purpose in Arcane Subtlety.
I don't like to go for increased range on spells (most fights are in a small room anyway...) and I put those points into Magic Absorption.
The 2 points in Frostbite are useless, put them into Imp. Frostbolt (You are going to need something to cast if you get silenced, ect. Reducing the time on a frostbolt seems to help more then giving frost spells a chance to snare.)
