Well, this was rather unexpected. I looked up around 36%, hunkered down and kept spam healing. After a few fail deaths later I looked up to a "WTF, we're at 6%?"
The kill itself was after the gongs were gone for a full air phase, and included Vishnushaman popping to finish off the last 250k (and then dying in a fire after we killed him, so that he couldn't rez us).
Nice way to wrap up a relaxing week. Glad you all know how to side-strafe.
