Probably monk.
Can the protection paladin use Divine Shield at the beginning of the Blood Rage phase
BrM is pretty amazing, because they bring one huge cooldown and they bring stagger, also if u have the rook trinket it helps aswell
Brewmaster -> Paladin -> other, as posted above.
Brewmaster is the easiest to do it on hands down, but any competent tank can do it.
I've done it on 10 and 25 H on a 571 Prot. Pally, and last week on 25 H with a 555 Prot. Warrior which was rough even with practice doing it on my paladin. As long as your dps/healers are capable of getting the tank the proper cooldowns it's easy enough.
Zen med => 2M guard + all personal CDs ftw.
If done right you won't need any externals, and most of the time not even a heal.
Therefore monk>>>>>all
Update on warrior soloing, did it again this week with 566 ilvl versus 555 and much smoother, not even a cloak proc even with going into the second BR with 6 stacks and no personal CD due to blood DK getting gibbed right before BR.
so easily doable with fairly average gear on any tank, definitely a total joke for any brewmaster even a fairly undergeared one.
Does diffuse magic work? Even without that Monks are the best by far.. with it, it's an even bigger gap.
We heal a couple of dks through 25H blood rage (one for each). However, we are running a lot of externals (2 hand of sacrifice, 2-3 ironbark, spirit link totem, power word: barrier, pain suppression for each phase).
Those are probably overkill, you should only need 1 - 30 % dmg reduction couple with class cds for the duration if using Rook's. 2 - 30% cds are plenty if you don't have/ don't use Rook's.
Probably druid and or BM monk my alt BM can tank it in 10m H easily.

Absorbs/damage reduction>heals, especially in this situation. All the other tanks have some sort of Absorb or Damage reduction while Druids have zero. In 25 man if you take any damage it is almost guaranteed to 1 shot you anyways. You will never get a chance to heal.
Being able to solo 6% of Thokk is cool and all but it really has no bearing on this. I'm not saying Druids can't do it because they can. Just answering the OP question and Druids are easily the worst for 25 H Blood Rage soloing.
we used to do it with a monk and I actually didn't have to heal him and could run around popping bubbles almost the whole time. now had to switch to a warrior and actually have to coordinate cooldowns properly. paladins sound very well suited for it too, but zen meditation is just a bit of a joke for that.
