I only made the comparison because Vigilance and Watchman are the two sustained damage Jedi Knight specs. They are different, yes, but Plasma Brand's overall, well, crappiness is quite an important reason as to why Vigilance is inferior to Watchman in almost every aspect.
Dots while lackluster are the tip of the iceberg when comparing vigi to watchmen.
-They have surge talents.
-AMFG raid Cd's.
-less conditional interupts.
-better survivability out of CD's.
Vigi really isn't a bad spec, Its just nowhere near as polished as a watchmen or even combat sentinel spec.
