So i walked around the neighborhood and collected about 9 survivors, maybe 11 and they are a unstoppable force, for everyone survivor you have, they can take on about 5-7 zombies in open space, so if we have 11 survivors, all together we can take on 55 zombies at once, it's absurd, they don't need rest they're basically terminators, except when it comes to sprinters, I'd like it if npcs didn't always join you or outright refused to under any circumstances, it'd be nice to have some decide to leave you if they aren't treated nicely, for instance i gave someone a shotgun, set it to their main weapon, and then let them stand in the neighborhood and have their last stand, Yes i'm evil but anyway it just seems like they lack the self preservation instinct and they are so powerful.
