Heres my armory The World of Warcraft Armory
Its a tiny bit out of date, i just got the Ablative Chitin Girdle - Item - World of Warcraft last night and stuck a 41 stam gem in the blue slot and a Thick Autumn's Glow - Item - World of Warcraft in the prismatic.
My main question here is that ive got alot of stam and i think i need to start gemming for more avoidance stats. Def rating, dodge, etc. Is there a hard and fast rule or no?
Also, why would tanks not gem for agi instead of dodge rating? A delicate dragons eye gives me almost ,9% dodge and some crit. A subtle dragon's eye only gives around ,8%
From looking at your armory i would say that expertice/stam gems would benefit you more at this stage. You got more or less enough health i aggre on that, but try to get about 25 expertice before you start gemming for avoidance.
