Eona from Durotan saw a picture of Drysc (perhaps via that very helpful faces of BlizzCon guide yesterday), and determined something that might surprise you: the CMs are people after all. Who knew?
But seriously, I've always kind of felt for the CMs-- they're given the responsibility of transmitting messages to the community without actually being given all the information. There might be all kinds of good reasons that your class buff didn't show up in the patch, and yet while they may even know some of them, the CMs can't just say it was because the devs wanted to wait until the Northrend expansion, or because they clashed with something you'll find when the actual patch is released in a few days, or because this really amazing item that hasn't dropped yet makes it irrelevant anyway. At times, Drysc, Neth, Eyonix, and all the rest can seem like the Iraqi Information Minister, but more often than not, I'd guess they're just not allowed to tell us the whole story.
So if you do see the CMs at Blizzcon, suppress that urge to run up and ask them why Shaman clearcasting got nerfed. Instead,
give them a hug show them your support in a completely nonphysical and nonthreatening way. Because while the CMs may play as NPCs, apparently they really are people too.
