Help Me Improve my build. SnB Commando

Okay so here is my SnB commando that I made a while ago. I forgot what build I was following but it was from vanilla. please any advice or what I can do to improve it would be much appreciated.

What DLC (if any) do you have? If you’re looking for builds, the compendiums are updated to the new forum links now.
You can also search on the tag “Commando” to get a good list of builds.
