D2 Noob... Is there a decent LMG Tank/Support build?

I'm SHD 40 and just farmed a St Elmos Striker build, and I've been mainly rocking a Tipping Scales/Pesti build (which I know isn't the best, but the ticks make my brain feel good), but want to try something more support-like.

Is there an LMG build that allows me to be a tank, so I can run up on enemies and melt them with either Pesti or Bullet King, while also providing some sort of benefit to a group like armor or buffs?
