In my opinion, you have far too many points wasted on passives. If you're going to do passives at all, pick 1 of either HP and SP (I'd say HP), and put very few there. You get the most bang for your buck with the first point. Some say to stop at 1. I personally have 3 points on HP with my level 29 SW, but frankly, I could have probably put the other two points to better use elsewhere.
Others like to put a point or two on Concealment. I think that's where you have some of yours. There's advantages to that. You can get past more Sentinels that way. But to do what? If you can't kill them once you sneak past them, you're not really accomplishing much.
Looks like your other passives are on ACC, which I don't get at all. Use gear for that. We're pretty accurate, even completely naked. If we had a Crit passive, that might be worth it (but not at 6), but ACC definitely seems like a waste of points.
But even if you kept three somewhere like I did, you'd have 9 more points that you could drop on Tier 1 or Tier 2, for example. This would make your attacks considerably better. SW is all about maximum damage in the minimum time.
