This is the build I had in mind, of course I still have 30 levels to go for max. The only thing I can pick out here is that missing 2 points in the Kolto Injection. 1 sec cast for a very nice heal at no TA cost looks pretty useful.

Do you have a build you can post to point me in the right direction?

As the title says, suggest me your best PVP Op build. I've been playing this class for a while and I absolutely love the idea of it, and I would like some opinions on good PVP builds. I've been going Lethality because I was told it is good in PVP, but now I'm thinking Concealment is better. I've also been eyeing some low-tier healing spec talents that look tasty for a gankster. Any suggestions, advice, and questions are welcome!
