I don’t know. I still think frost is difficult to play very well. Simply spamming ice lance does not put you above others. You have to make that mastery work for you. Only way to do that is casting frost bolt. you have to know how to use your procs. you can’t just simply use them as frost. You have to build up to get those extra icicles.
icicles turn that ice lance from a 60k spell to over a 100k.
