So this happened a while ago... our main tank and GM decided that he wanted to take a break from wow... leaving us a tank short. I am a Druid healer normally, well was. I healed BC, and Wrath up to ICC. In ICC one of our tanks took a break much like what is happening again. I was allowed to step up to tank ICC as a bear, and later after I quickly leveled as a DK, due to a better raid make up. So once again I am to be a tank! (thank god! I love it, tho I do miss healing now and then) and I have been tanking ever since fire lands using the old stam stacking idea since I havent seen huge amounts of theory showing Agil > Stam... but have read that Stam > Agil on heroics (which we are about to start).
Anyways Long Story Short. Our other tank is a Warrior. We have most of the buffs/debuffs covered. 1) Should I stay on my bear or play prot pally or dk (for better synergy)? 2) Can someone link me more information on Stam vs Agil.
