I am working on my tank gear set and I have finally been able to get thru heroic dungeons without too much trouble as long as the group is good. Link to my armory: Conanobrian@staghelm
I do not have any gems yet b/c i've been replacing gear but now that i have some semi perminant stuff i'd like to gem it. My main concern should pbly be stam right now as i have about 127k i think without buffs. After buffs i hit about 160k with luck of the draw and shout.
Also i know absolutely nothing about gems. never used them.
