I actually LIKE shotguns for pve. It's the best backup for my MIDA which can basically hold its own. But my vendor-version secret handshake is just awesom in those' tier two melee-knight running for you and your mag is empty' situations. Shotty to the face - move to next target. I hate using fusionrifles and sniper's redundant when wielding a MIDA. When using any other primary I generally use a sniper instead
