For what it's worth, Apathy popped AV again yesterday. We did two things: First, we fought with a rotation of a WHM PLD and BLM popping 2hrs when AV did 2hrs. He didn't use any of those 2hrs afterwards, but after we were out of 2hr rotations to do, he did Manafont and wrecked us.
Afterwards, we decided to test out all 15 jobs being in alliance and using 2hr. Pulled him, he did SAM 2hr, and all 15 people did their 2hrs (DRG did Call Wyvern then Spirit Surge). AV used Mighty Strikes like, 30sec later. The chat logs were examined, all 15 people did 2hr, and the WAR was confirmed to have been near AV when he used his. 2hr lock confirmed to be a no-go.
