This build was originally inspired by a youtube video posted by swingpoynt, linked here:
This is currently my Moze build, and has taken me through the raid on M4 successfully. Iron bear is still only used for the occasional "oh shit" moments, but not for much else.
Gear: centered around the handsome jackhammer SMG(must be shock) and transformer shield.
Cutpurse deathless relic is a must, I'm pairing that with the bloodletter COM maximizing thin red line and desperate measures.
Great rolls to look for would be SMG damage, weapon damage, shield recharge rate/delay or whatever else is fun for you.
