A casual gamer should not have to setup or join a group, even if it with other casuals. This idea will making banditry and hoarding even worse, as Zombo said before.
This is what I was just thinking. Crawling through elektro. I would much rather have a melee weapon as my sidearm then a pistol. It's the worst to run into bandits or other unfriendly people while you have only your hatchet on and nothing with some real firepower to defend yourself.
