This is not politics and you don't get to wiggle your way out of the fact that you were dead wrong about breath. You can't claim anything after you say shit like even tanks can't survive breath which is outright BS.
Yes I used Unending Resolve... do you know how much HP I had in my lowest point during the Breath? 1.9 million HP. If I would not use Unending Resolve, I would still survive just fine and that is with the worst possible Dark Pact from Imp at that. Get this in your head and cut the BS already!
Thankfully, since I am a Destruction Warlock - I am blessed by 1 min CD Unending Resolve as well to completely block shit as well in conjunction with Dark Pact and Soul Leech, so not sure why you try to waggle finger at me for using that at right moment.
If I would be Demo I would have Soul Link and jacked up Dark Pact as well and as Aff - you would have a ton of extra healing and 3% extra shield at top.
In short - you can survive it fine even without Unending Resolve, as any warlock spec by popping just Dark Pact and rest letting passives/or selfhealing handle it as can be seen from that log.
But really, you saying tanks can't survive this just sealed the deal - the thing does like 2.5 million damage in total and over 5 seconds channel at that - it is nothing really for a tank (or a warlock) in a grand scheme of things, when as a warlock you absorb north of 20 million damage in any decent Mythic encounter and reduce hell knows how much with proper UR use.
