My thought is that if the enemy is that close, I've done something horribly wrong to begin with, or I'm running the lamps. Either way, I still think they're not ideal for pve. Fusion rifle is still a much better choice, even with the wider dispersion cone.

My son picked up universal remote from Xur Friday. We tried a few setups and found running a high impact sniper and a heavy machine gun with it worked pretty well, but you have to really monitor your ammo. With the maxed range settings, as maxed as we could get it at the time, It was good for the short range. We used the sniper for long range and high damage to make up for the heavy slot. The machine gun was really needed to cover mid range and high enemy count situations. Still not recommended for end game content though. Still wouldn't want to run a short rage shot gun either. Way to up close and personal.
