i've gone 0->375 LW just for the windhawk set (as a resto druid). The bracers are awesome, the belt is great, and the chest (when used to complete the set) compares to the restoration t5!

Then you add the +spelldamage (if you're a dreamstate build), and its just perfect. Druid gear at its best, great for moonkins and trees/pvp healers alike :)
