Updated Builds for 7-Hero No Cons UW ("Dhuum" Demonstration)

Thanks to Master of Damage for simulating Dhuum.
Someone got me thinking about updated builds for UW. If I were to attempt the 7-hero UW runs again, I would probably use these builds and kill the mesmer heroes with dual vamps/superior runes/grim cesta (couldn't afford dual vamps a year ago, hence the usage of Order of Pain and Illusion of Weakness).
These builds have two major improvements over the previous builds and one minor drawback.
Improvement 1: There's no longer a Me/R with significant point allocation to an auxiliary attribute. All mesmers in this build will have 20 dom and 19 FC.
Improvement 2: The hero that maintains QZ at Dhuum needs something worthwhile to do in between QZ casts. All a Me/R can do is spam Unnatural Signet - anything else would lead to energy issues. Meanwhile, the Rt/R can maintain Brutal Weapon on most of the party and maintain Pain (both of which are also useful at other points in the run).
Minor drawback: Fall Back on two mesmers may cause some energy issues, and during 4H I'll need to make sure the other Me/P is maintaining Anthem (when engaging enemies, backline such as ST tends to be better at maintaining Anthem than midline).
