Sir Georgeous here, and I came up with a team using zAsajj and she kills it in phases 3 & 4 of the HAAT. Over 200k on her basic, and both phases were soloed in 30 minutes.
I created a video showing my run and explaining how others can accomplish this too, even without insane mods (mine are average).
I hope this is able to help people! I will be posting more videos in the near future
