I came across this video over on the official Rogue forums. As the author, Loz, clearly states -- this isn't meant to showcase PvP skill, only large crits, so don't expect to find anything but one-sided fights. He's well geared, he's got a mean dagger, and I found the video extremely entertaining. The video also makes me more anxious than ever to try out Shadowstep again in Patch 2.3.
But, if you enjoy watching lesser opponents getting their faces melted in 1.6 seconds, this is the movie for you.
