I have heard legitimate talks for both specs. I am kind of coming back to WoW probably full time for a couple of months at least and really want to pvp. I love frost but I have heard unholy is better. What are your opinions and why? Thanks.
If you love frost, stick with it. Unholy might be theoretically better but frost is viable up to 2.2k at the very least, if not more, and it has a lot of advantages over unholy as well, biggest ones being burst out of the ass, COI roots and hungering cold.
