As a Shaman, I'd take this over the Chitin mail any day of the week. Though If I had won the Chitin mail before hand it is droppable and I would gladly make someone elses day and hand it to someone who needed it. The only fighting is gonna be when greedy people win it is all ;)
Though I'm wondering why Rogue made it, the ac is great but it lacks dex and I've found a high dex as a rogue is really really good (168 on my rogue and he procs his spear atleast once every fight, have had up to 6 procs a fight).
Great Ranger Tunic, but I wouldn't stand aside on the rolls for it.
so the only people who'll really be butting heads are shammys and rangers ;)
