Hello there, I havent been reading tankspot a very long time but I have been playing since beta. I saw your question about a frost spec and I wanted to share mine with you that plays wonderful. One of the ideas of this spec is the frost strike is to be used as an attention grabber or if you are full rune power to just not let it overfill and waste the power.
I will be happy to show you my rotation if you would like just let me know.
Here is my Armory Link and I am always welcome to input from Tankspot people due to you guys are wonderful and I always learn something when I am here.
