we dont need to be healed any different than other tanks
but we have 2 mechanics which makes us completly different than other tanks
with stagger, ISB and PB we got the smoothest damage intake of all tank and by far of all tanks. no spikes witch gave Healers instant heart attacks
with celestial fortune any HOT is significant stronger (given your BrM has some Crit gear, some BrM play with more Haste and Versa, so it depends)
our Mastery is some depending and with good raid gear we avoid every 2-3 auto attack wich is huge
we dont need snap healing and be instant topping back to 100% because the next hit could kill tank BUT we need constant healing and there comes Celestial Fortune into game. With Hots and Crit we can most of the time negate the ticking stagger damage
it is, in my opinion, the closest to a perfect Healer-Tank-Relationship. Give us passive healing from healers and nothing will ever kill us without straining the healers sanity. But you have to play with your healer and with your Brew-Charges. And you have to know how much damage you can take and also when you have to PB so that your healer dont panic heal you back to 100% because you suddenly drop to 50% which isnt a dangerous heal-level for us at all.
