Yes yes, I know Razorscale is already really easy.
But during the first week of Ulduar we discovered a unique way to do the encounter that made it idiot proof.
Took awhile for me to stop being lazy and make the video.
This is meant to be more of a supplemental video to strat guides already available, so it doesn't cover every little detail.
Watch, and enjoy.

also this isn't a "perfect" kill video, there are mistakes made, and plenty of lag to go around. (yay unstable servers)
edit: for those of you who are at work/not able to watch, I will do a quick sum up for you.
Basically what is happening, entire raid stays out of the red circle. Sentinal tank stays in the middle and kites the devouring flames, which basically takes them out of the equation for the encounter.
After Razorscale lands, she will fly to the northwest corner, sentinal tank must follow her to continue to kite the flames. Once first harpoon is activated, she will be dragged back over the middle, tank must follow.
Raid groups up adds and aoe's them down, continue encounter like normal.
