If you look on the right of the link you posted it would appear it is from 350 Synthweaving.

The good tanks didn't have a problem with him either. I surely didn't. I already mentioned 4 interrupts with weaving Force kick in between the others. Interrupt everything and this fight is a joke. Example of interrupt order: Force Kick Force Stasis (I always follow it with a Pommel Strike/Master's Strike Force Kick Force Push Force Kick Hilt Strike etc etc etc Use your cooldowns while companion is alive. If Guardian spec, you should have zero reason not to kill this with Saber Ward, Call of Focus, Saber Ward again, Warding Call, Enure, Medpac....do I need to go on?

One shot it at 34, Defensive specced, moderately geared. Honestly, I thought it was a joke as I never went below 80%. Saber Ward, Call of Focus, Saber Ward, and used 4 interrupts with my Force kicked weaved in on cooldown.
