Alright, so after going Ranger/Assassin/MM for the longest time, I decided to make my 2nd role a melee dps build as MM sucks right now and i'm not putting out enough dmg.

I really like the sin soul in general, so I spec'd my rogue with Sin/NB/BD

I'm not lvl 50 yet, so I can't say what the final product is, but can anyone help me with the build and point out any unnecessary points?

Right now, I like that I have stealth and slip away for ganking and getting out of ganks. I'm just afraid that people will run, and I can't do anything about it, which is why I put the points into improving twilight force. I just feel like there's something in this build that I really don't need and can be better spent.
Thanks for any help in advance!
