Hello, I'm one of my guilds main/off tanks we are doing ulduar 10/25 and ToC 10/25 if I should just stack stam rather than avoidance for those places because bosses are hitting alot harder. I currently have 48.19% total avoidance and 29421 hp unbuffed, I was thinking about getting the 2 new 170 stam trinks from the brew fest also here is the link to my armory, The World of Warcraft Armory
My philosophy is to always gem x+stam, or pure stam. Gemming for avoidance is fine for a specific avoidance set, but bosses tend to hit hard in ToC. Also stam is your only buffer against magic attacks. For a comparison I have 39k unbuffed, I only match socket bonuses if it's +9stam, otherwise every socket has a +30 stam gem in it.
