You can see the Orgrimmar version above, and the Stormwind version past the cut below. Neither video does the chaos of the event justice, but no video ever will. It's something you need to be there for, I think. No video gives you the "holy crap, did that just happen!?" feel of Varian Wrynn leaping through the air and tearing an abomination asunder. The fight between Thrall and Garrosh is ridiculously cool, too.
I highly recommend trying to see these events before they go away, but these videos will do for now, and our thanks go out to Chrono of Silvermoon-EU and Ben H. for them.The battles against the Scourge in Stormwind and Orgrimmar continue to rage (once every 20 minutes), but if you're not in a position where you can see the event firsthand, some fantastic readers have contributed some videos for us, and for all of you.
