I love my vig guardian. I used to be a focus stat sheet whore who only cared about damage and crit size. Then I realized that doesn't help your team and isn't even that fun. I can literally pull MORE damage with this spec because I die way less.
I feel unkillable. Commanding awe talented focused defense is so sweet - I literrally can begin fights with squishys and pop enure/rakata medpac and let FD tick and end the fight with more HP than I started with.
I am un cc able when I leap around, and yet I spam AOE slows with no focus.
I roll in Soresu with 52% armor and 1703 strength buffed and cut through sh*t. Any light armor guy is getting white-washed by Overhead slash, master strike and dispatch, while any heavy armor fool is getting DOTted like there is no tomorrow.
Focus generation has never been an issue, and with defiance and zen strike I get free focus for days.
This is my spec, hear me roar: http://www.torhead.com/skill-calc#500RrZfzrMrhddGkZM.1
