This post is as much a personal question to help out myself, as it is to try and start a little debate getting some views on the future of frost spec in raids.
After the big buff to frost in 7.1, i have been building up a frost spec beside my normal fire spec, as i think a few of us have done. On single target sims there can be no doubt frost is superior, but fire is still stronger on some fights like Il'Gynoth, Dragons, and arguably some others as well. I also know that many mages will continue playing fire, seeing as they have put alot of AP into it, and probably also have gotten BiS legendaries for it.
Question is do you guys think it is worthwhile for us mages that haven't gotten any BiS legendaries, and have a decent frost spec already to start playing frost as a main spec, seeing as it might be better for raiding in the future?
Side note: This is purely for raiding, we all know that fire is the best spec in mythic+
