I play a hunter named Kripparrian on Ysondre-US. Since I started raiding hardcore with Ulduar, I have held most of the top DPS parses on wowmeteronline.
This video outlines the basics of what is required to achieve #1 DPS parses. I discuss general DPS technique, not ways of specing, gearing, or gemming -- which are less important factors -- contrary to popular belief.
