This is very very extremely wrong.
 
	1. 5/5 winter's chill is useless. Blizzard doesn't crit, so the only significant spell this affects is CoC, and even then it's negligible since normal mobs will be dead before you build up enough stacks to notice it.
 
	2. 5/5 improved frostbolt is useless for AoE grinding because you don't use frostbolt. Even if you did, it's not as good as it looks because of some GCD and spellpower mechanics
 
	3. Cold snap is 100% essential. When something resists frost nova, you can just cold snap and re-nova instead of resetting, saving you all the time you otherwise would have spent running away, eating & drinking to full again, and then throwing your keyboard at a wall because some other mage stole your pull while you were resetting.
 
	4. Improved frost nova is 100% essential. Frost nova is one of the most important spells you have. Without improved frost nova, after casting 2x blizzard, you'll still have to kite everything for ~2 seconds while you wait on nova to come off cooldown.
