The medigun backpack, after hitting a certain amount of durability, will refuse to let the medigun function at all. I know it's meant to function as the ammo for the medigun, but between that and running out of durability in the medibackpack mid fight(and thus being unable to heal my npc minions), it's rather annoying to use the mediguns at all when the dispenser just... has infinite heals for the low price of 100 metal?

I think Rafradek was kind of going somewhere with the ammo like that, but I'm not sure what he was thinking with the medigun backpack... >.>
