Don't answer terrible posts, just report them.
The drastic loss you saw in your dps losing Windfury definitely cannot be attributed to being frost sub-spec alone. Doing a sim of my own gear and removing Windfury for both a frost and a blood sub-spec, both specs lost a similar amount of dps (763 for blood and 727 for frost) when removing Windfury. I'm not going to clutter this up with a copy paste of my results because you can just as easily do your own sim with your own gear. Making conjectures based upon your performance in a single 10 man in comparison to a single 25 man raid probably does not give the most solid results.
