http://forums.wow-europe.com/thread....05842304&sid=1 <---- Moonkin Tanking Guide. It is pretty good.

I have actually tanked thru Crypts with my Moonkin (while wearing cloth gear) thanks to the 400% armor benefit. Starfire is a great aggro generator. And Moonfire and Insect Swarm are great instant cast aggro generators when tanking a lot of mobs at once.

And when you need it Barkskin can work wonders. Sure they are not tanks in any traditional roll but they are fun if you have a good group (or boxing).

I am mixing in a Moonkin into my Shaman group. With the Wotlk buffs such as the new Moonkin haste aura, Earth and Moon and removal of the long Hurricane cooldown they are going to be a blast.
