Questions from a new player and his wife.

We just got the game together since it went on sale on steam. But we've had a few troubles that Google just has a hard time helping with, maybe I'm typing stuff in wrong when I look up something I just dunno, so my regular large camp keeps downgrading from a large camp to a small camp when we join another possie for missions...

Also what's the 4 ability Best cards for us? Like what should we strive for? We usually try to run away but when it comes to surviving if we have to actually pvp what can cause us to live longer and deal with them, we both suck at free aim but we're on pc so it cant be just God weapons that headshot.
