I decided today to experiment with Frost dps, considering I've seen so many complaints about how OP it. Maybe I was doing something wrong, but I was only managing to pull 1300 dps with Blood Presence on using http://www.wowhead.com/?item=44250 x2.
This was the build I was using: http://www.wowhead.com/?talent=jfV0VZG0exhxdRhoVosxf
Any feedback?
