Getting refused to EX groups as a DRK

[Ipkonfig]

On paper, Thrill + Conv looks like decent "mitigation" but in reality if you take a tank buster with only those two up it's going to be a big chunk of health, most likely causing an emergency reaction from your healer. Healer's emergency heals, outside of Bene, are abilities (Essential Dignity, Tetra, Lustrate) and are unaffected by Convalescence, or Defiance for that matter making them less efficient means of healing which requires your healers to spend more time/mp to boost you back up.

And all the pairings of IB with different cooldowns insinuates you have 5 stacks of wrath ready to rock, which is possible, but would most likely require you to sit on 5 stacks till you need them which really reduces WARs potential, and using Infuriate should be done at zero stacks so you don't waste what you've already built.
