Meteor is an excellent and under-used cow-killing skill. It truely works just as fast as nova but doesn't require a crapload of points in warmth.

Also, 200%mf is all you really need, this sorc is extremely buff with over 10,000 armor easily, and 75/85/75/75 resistance in hell, with plenty of mana and an average of 1200+ life. What's not to love about her?
