Altered Time - your #1 World of Warcraft Mage resource!

I switched to frost recently after struggling to perform well with fire after returning to the game (didn't have bracers.) I'd be grateful if someone had feedback on my logs. I think I understand the core concepts of frost but my parses are utter trash. Thanks in advance.
