How Does Affliction Warlock Compare in Prolonged Fights vs. Burst Specs?

I know Affliction can’t shine when things die too easily, especially when there are classes like Outlaw, Fury, or Windwalker in your keys

But how much better can Affliction be when things take a while to die compared to classes that don’t need ramp-up?

Especially with so many things getting thrown at my feet in War Within dungeons, when I’m busy dodging puddles and these bursty specs, which aren’t stationary during their rotation, are busy finishing off the adds

And there are so many mechanics in TWW Dungeons like continuously throw puddles at your feet, it can be like setup Seed → Vile Taint → Soul Rot (puddle mechanic) → Cancel cast → Soul Rot (puddle) → Cancel cast
And I have already wasted 4 seconds on Vile Taint there

So it also got me wondering, am I supposed to be doing more damage when I’m not moving compare to the other classes that have the mobility?

There’s no data following the 5 second internal CD nerf on our wither stacks, but prior to that affi was one of the top AoE dps specs in the game in keys on beta and logs.
