I mentioned in another thread that I'd talk about Thorim Hard Mode.
Our healers have found it significantly easier to heal 1 target than heal 2 tanks when swapping, they don't want to risk the current tank getting gibbed by Unbalancing + Parry haste + Frostbolts or whatever, but at the same time, the 2nd tank takes a huge risk when taunting of heals being slow to come in. After my success in 10 mans with the glyph of barkskin, we (I) decided that I should solo tank the 25 man with crit immunity gear.

Thus far we've seen the enrage timer a couple times, we're still bringing 3 tanks (mistake) melee keep chaining the lightning and ranged die to blizzard+frostbolt volley. But, so long as healers (and the various paladins) don't die, I've lived through 18 stacks.
This is just one way of doing it, that I sincerely hope will work, I know a lot of guilds use other methods which switch tanks around (specifically DK's and Warriors), and I've heard of just using double Druid to rotate barkskin crit immunity (you do need 4t7 to cover the full debuff though) If you have healers that have trouble target switching, I do recomend finding a set of gear similar to mine (all the better if you get furious pieces over deadly, the +20 ilvl is huge)
And yes, I do realize there's
[Arcanum of the Savage Gladiator] which would probably be superior to using the chest enchant

At 0.1% of my healing received, I'm sorely disappointed with Blood Draining, my health was dipping faster than it procced. Because it doesn't actually prevent damage (like mongoose, and the amazing Blade Ward) it really doesn't seem worth it as a PvE enchant, and you really aren't going to see it in PvP. Much like Savagery, Black Magic, Scourgebane, and so many other enchants, it's another good idea, poorly implemented by blizzards "if it's clearly the best, then it must be overpowered" team. There was nothing wrong with Mongoose being as good as it is, putting in a Greater Mongoose isn't going to break the game. I'd even take something like the proc effect on the SSO neck where what you get could vary based on class.
