It really is that simple. If this is simply a case of Blizzard playing it safe while they investigate, there should be nothing incriminating in the video you undoubtedly recorded of the encounter. So, let's see it.
I'm willing to give Ensidia the benefit of the doubt here. In the past, Blizzard has in fact banned first and asked questions later, as they did to everyone online in the guild of the individual one-shotting Ulduar bosses with Martin Fury. And yet, I find it a little suspicious when it's become so commonplace for these guilds to publish videos of their successful attempts, that there's nothing of their successful attempt with the last boss of the expansion.
