For comparison, using myself vs Ariellè for monk vs bear
A 1M damage hit on both of us would deal 179,317 after shuffle (w/mastery)+armor+native DR for me, and 230,958 for him. I know raid buffed w/food+flask+shaman buff I peak just over 1m hp. So even if we're both at 1m hp, he takes a large chunk of health per hit than I would. Then again, I'm also at 14k+ mastery.

Exactly. I pushed myself to 14k mastery before buff so I could easily tank Malkorok with just the Malk trinket. I'll probably drop 3k mastery for more crit. But I probably wouldn't ever go below 11k again, higher mastery just makes me feel better. I am of the "stay alive and take damage" as opposed to "I DO THE DAMAGES!" camp. As I get more and more on farm, I'm sure I'll slowly move back towards crit but probably not until Garrosh 25H is down.
