DP/DEV Build Advice required

First off I haven't added in any enhancements as I've only recently come back to the game after a few years and don't know much about IO's.

So this is the build.

Your picking the lowest DPS set with the Weakest secondary. IF you can get S/L and Ranged Capped then regardless its all good. DP biggest DPS attack is PBAOE. I can see you getting upset eventually with this build. Don't do it.. I don't think you can get the defenses your will need with this build.

If I can suggest DP Traps Defender. You can get all the defenses you want capped. You can walk in drop Rain of bullets, have the mobs fall down, Drop a Trip mine and kill what ever is left OR RoB, then Poison Traps, then Trip mine. I have a Sonic Traps and I will tell you, without a doubt you will be golden and loved by everyone on the team. You will be able to solo +8+1 with no issues.
