Warrior MT at a disadvantage in O3S?

It's easy to say "healers should do better and focus heal at these parts". But I'd rather be proactive, and figure out if there's a way I can improve, or if the class overall needs to be improved.

You're referring to the basic and age-old disadvantage of Defiance which is present in all content and that is that it is only functional while being healed or when you are at full health. If you are in Defiance however, you have IB, and WAR's mitigation kit smokes the other two tanks'. Your mitigation suite has insane uptime and is completely costless with the exception of IB, which is really only there (along with Equilibrium) to make Defiance's aforementioned disadvantages largely moot. An unpopped TBN after the books will still mitigate AAs if it lasts long enough (remember TBN is only 5 seconds, in fact if you pop TBN immediately prior to the books you're almost certain to have just wasted 1/4 of your mana), but so will ToB, technically, since you will still be left with more HP to take those AAs.

Assume a DRK/PLD and WAR that are all in tank stance and at full HP when the book hits. They all have 50K HP at base. 50K HP in Defiance is 62500. Assume also that they take a 15K AA after the book.

DRK/PLD: 50000/2 = 25000, 25000 - (15000*0.8) = 13000
WAR: 62500/2 = 31250, 31250 - 15000 = 16250

13000 is 26% of 50000, and 16250 is 26% of 62500.

So, every tank got left with the same percentage of their maximum HP remaining after eating a book+AA.

So the job is not at a disadvantage.

Fair enough. Inner Beast doesn't help when Spellblade +books hits, since it needs me to be standing on next to the boss to use, but it's a minor gripe compared with DRK's overall DCDs.

I probably do need to just "man up and get good". But with servers down, this is all I can do. Run some calculations, and see what other people on the forums say.
