I've done it. The more I play Frost the more I enjoy it. The RNG in unholy doesn't change the fact that it isn't reactive - it's just frustrating. You have choices but those are purely based on shit-streaks of bad luck and "FFS" moments rather than good ones. Frost artifact at 868 (898 UH) because of crap relics but it's already pulling way ahead in damage as a spec and aoe is instant which is another big plus. I'm looking forward to developing the spec and seeing where it goes but I have to admit I am enjoying it more than I thought I would...
