Hello Everyone!
I have a quick (but possibly extensive) question.
Basically I solotank Garrosh on my tanks every week for looms - And I'm trying to squeeze the maximum amount of DPS possible out of them (to make the runs as easy as possible! solotanking, even with 7 mediocre DPS, makes the fight trivial), the class I do this best on so far is Monk for various reasons, which have alot to do with Monks doing extremely good damage for little effort and the ease of soaking Annihilate.
I play 3 tank classes; Warrior, DK and Monk.
On my monk, soaking all these is easy. I basically go Zen Meditation (soaks 3), External or Fort Brew (soaks 1-3), Diffuse Magic (soaks 2) and a 1 million+ glyphed Guard takes the rest for me.
On the other two tanks... not so much, when solotanking on a friend's DK who has a stamina trinket, I noticed I could stand in every annihilate (except 1, which I stood in and died from full HP, without my tank cloak proccing. if someone could explain why, I would be greatful) without a single CD, my tanks cannot do this, because I take offensively orientated trinkets (aka Thok's Tail Tip, Skeer's Talisman).
My question is: What % of damage reduction or # of absorption do I need on the following 2 tanks
882,000 HP Blood DK
735,00 HP Warrior (Though, should increase when I get the cloak)
My guess is I need 1.375M EHP to soak them before tanking damage reductions, but I'm not sure how to calculate damage reductions stacking ontop of eachother (my maths is rusty). My guess is I need about ~25% DR on the Warrior after Def Stance, or around 300k~ absorption, and quite a bit less on the DK, but a helpful hand would be greatly appreciated.
I don't need to really save my cooldowns for P2 DoT - I usually have 3/4 usable externals or just don't need them at all because active mitigation negates a huge portion of damage I take at those damage levels, so I can use them as I see fit in the heart to get 600k+ veng which improves my damage by insane amounts.
edit: what seemed to have caused my death on my friends tank is lack of bone shield, overkilling me by 16k HP (I have it macroed into death strike luls), still, tank cloak didn't proc, odd.
