You've seen him tank Shahraz and a 5-man Gruul run, and now Gaeowyn, of the Shards of Existence guild (US Illidan-A), has struck again. Technically, he gave us some teaser footage about this back at the end of his Shahraz video, but he's now released a full video of a successful Illidan tanking. As on his last 2 videos, Gaeowyn was able to use gear, talents, and buffs to stack enough dodge and parry to fully avoid all physical attacks (with a little help from Scorpid Sting and Insect Swarm, of course).
Alas, it looks like this will be his last video. He says that he doesn't want to wear out the concept -- after all, there's only so many videos you can make of a rogue standing in front of a giant monster and dodging a lot. In addition, he's switched characters to a priest to help his guild with a shortage of healers. I'll miss the series, myself, if only because it's great to see people conquer challenges in unconventional ways. It makes the game a little fresher and a little more interesting.
[Thanks for the forward, Allen!]
