Which is more beneficial when gemming stamina or avoidance. Personally I have been gemming for avoidance 8dodge/12stam, 16dodge gems. I see more and more warriors gemming for stamina. Is stamina a better for boss encounter in ulduar and such. Sorry if this question was already asked somewhere else. The World of Warcraft Armory
You are over 45% dodge/parry. I would gem pure stamina.
If you insist on more avoidance, Satorri has already tossed out the optimal ratio of Dodge/Parry to be about 1.85 to 1. Depending on to where you are on the diminishing returns curve, adding some parry or Def/Stam may give you the most bang for your buck on avoidance.
But as always, do your own math and draw your own conclusion.
