I'm a "terror"

tank myself. And can solo Ice Wastes, Chaos Planes, Bone Pits & Spawning Pools. (And while my opinion is definitely biased), I believe any ectos I get while doing that belong to me as I'm doing all the work for them after all. And it's not like the build is super-easy to run, as one mistake probably means instant death.
And like others have said I could always just get some heroes to get me past the Aatxes if I wanted to.
Now what I really want to know is - what are these 30 min UW clears I'm hearing about

? 30 mins to complete all the quests AND clear all the areas?
Someone please enlighten me here - as it typically takes up to 30 mins just to do the smites run alone...
