Xenophage right now is decent in most Pve content in the game. I would like to see it be actually good or maybe even great. The number one thing I ask is let it hit critical shots. It makes very little sense that it can't right now. It seems it has a powerful version of explosive payload, but every other weapon with explosive payload can hit for crits, so why can't this one? If for some reason you can't do what's suggested above, then I ask you to either buff damage another 20-30% or give it 40 rounds in base reserves and let each machine gun reserve mod bump that up +5. Maybe if you apply one or maybe even two of these suggestions, it would take the xenophage from meh/decent to good/great.
