(translated to Guardian's version)
ROTATION
================================================================================

Opening

Saber throw > Force Leap > Master Strike > Plasma Brand > Combat Focus > Overhead Strike > Blade Storm > Master Strike (on proc) > Dispatch (on proc) > Sunder


Priorities
1) Relic+adrenal
2) Blade Storm(this must be 2 stacked so plan your shatter, impale and vicious throws around it(try not to over stack))
3) Master Strike
4) Plasma Brand(the Plasma Brand DOT does alot of damage try to keep this on CD)
5) Overhead Strike
6) Dispatch
7) Sunder (Using Combat Focus in place of sunder works well)
8/ Saber Throw (with set bonus)
9) Force Sweep(this generates 1 rage so use it instead of an assault(until I test out more)
10) Slash (there are rare times when the amount of focus you're about to generate from sunder (builds 7) will push you past 12 focus so use one to make up for that if everything is on CD)
11) Strike



Sub 30% Priority (this is where the Jugg/Guard dps shines)
1) Dispatch (due to the reproc you will get some double Dispatchs )
2) Blade Storm
3) Master Strike
4) Plasma Brand
5) Overhead Strike
6) Sunder(Combat Focus in place of Sunder)
7)  Saber Throw (with set bonus)
8/ Strike

Vigil is so useless in pve.

Which still makes absolutely no sense since it seems designed to do so much better than Focus.....but it doesn't......

EDIT: After reading that guide, I tried Vig again with my utmost effort, and was able to change my rotation to where I never ran out of focus, was able to use OS, PB, and BS every time they were off CD, which I previously had issues with, and STILL could not sustain over 1380 DPS. Switched to Focus and sustained 1450 with out even putting in effort....
