This has been discussed. Perhaps you should read that discussion.
So with 3.1 here and all, what are the current "Best Practices" for a resto shaman? I've normally valued Mp5 and Haste over everything else. I've also very rarely used HW if at all. Does that change now? should I switch out stuff for cirt gear (which I collected anyways for occasions such as this)? Do I start using HW in place of my LHW for my normal "Go to" spell if I dont *really* need the speedy casting of LHW?
