Hey Kao, I've read your guide and believe I have good candidate for a sticky on the WoW Shaman class forum.

Baelnic has written a good guide for gearing up restoration Shamans and is constantly updating it. I nominate it to be stickied in our forums as it will only be our second one. I just don't want to lose it off the first page!
Cheers.
