This is probably a bad idea, but what if the Phlog had to recharge to fire? That way, players would have to think about what they're doing instead of rushing into battle head-first. The Phlog's description says it takes energy from a living being, so how is it replenished by ammo-crates? Ammo-crates aren't living I think. Too underpowered? Wrong thing to change? What do you do think?
