If you looked at the video though, Sen, you would realise that the video he posted was from November 5th. 2 and a half months ago. He pretty much had a perfect run and was above the Black Mage. Although the SCH was using EoS which is a quite a big DPS decrease for a BLM. The discrepancy between your gear and his gear in time is probably the main thing. I'm certain that Lamia his DPS will be a lot higher by this time considering his dots never fell off, his Shadow Flare was up pretty much all the time, he baned both adds and LB, and spent almost no time with no MP. Although, as you can see he has to use energy drain like 5 times.
