It really is about time the prowler came back to ground loot. I get it because in the real world a submachine gun firing a heavy cartridge isn't really a thing but its a cool gun that I have rarely had much chance to use for ages now. The triple take doesn't seem to fit as a care package weapon. I often used to pick it up early game as it was pretty easy to use close range from hip fire like a shotgun but would you take it late game from a drop over what you currently have or instead of a Kraber? I probably wouldn't. I think one of the shotguns should always be in there as well, with the EVA 8, the Peacekeeper and the Mastiff along with the boosted Mozambique we are overloaded on fairly similar weapons now.
I would just stick the Mastiff back in there and put the bow in there. The bow just seems the sort of weapon that should be rare and they could get rid of all the arrows littering the floor as well.
