I'm using http://www.torhead.com/skill-calc#400bsrbdMcRgzZbcZG.1 Marksman-heavy build. Up to level 48 so far so it's mostly filled out and working well. For leveling, I've put two points into Cover Screen for better survivability and skipped Pillbox Sniper - which may or may not even be useful at 50. It's also debatable if Deadly Directive is worth the points, as well - I'm thinking the points might be better spent in Calculated Pursuit. On a related note, I would kill for a talent that made Debilitate even a 20m ranged attack... perhaps a regular passive ability for going with Sniper, much like going Sorcerer makes the Inquisitor lightning attacks longer ranged.
