I've been thinking about trying a Vig build purely for PvP (PvE be damned, I'll respec back to tank spec for that) and after playing around with the builder I think this spec seems pretty decent: http://www.torhead.com/skill-calc#500zMZhrrMrhddMRZGb.1 Since you have more experience though I'd welcome a review and critique.
*I should add I still plan to run around in Soresu form mostly, hence some of the choices for point placement. Master Focus (because it might seem odd) is simply for the 10s reduction on stasis.*
