Just hop onto the Patch 3.3 PTR this Wednesday at 4 PM PST/7 PM EST and put your character into the random heroic Wrath dungeon queue. If you're lucky, you'll get grouped with someone with <GM> before their name and get to run a heroic with a dev!
This could be your only chance to use that funny quip you've been saving for a blue post reply, or to make sure that Ghostcrawler never lives down whatever off-the-cuff comment he made one time that everybody interpreted the way that they wanted. Just make sure to say it while he's busy doing something. Timing is everything.
Oh, and some WoW.com staff will be there too. So get your PTR client patched up and ready to go and let's. Get. Random.
Patch 3.3 is the last major patch of Wrath of the Lich King. With the new Icecrown Citadel 5-man dungeons and 10/25-man raid arriving soon, patch 3.3 will deal the final blow to the Arthas. WoW.com's Guide to Patch 3.3 will keep you updated with all the latest patch news.
