>Don't know how to properly reward nat20s
What system are you running? In My experience, there isn't really much of a need to "reward" lucky rolls like that anyway if it's something mundane like cracking a chest or forcing open a door.
>Hearing there's 7 bandits at the camp, barely surviving the first 4 and then deciding to take a long rest in the 7 beds before getting wiped by the remaining 3
I'm glad to know I'm not the only person this kind of thing has happened to. I don't think there's anything wrong with pointing out the flaws in this way of thinking, just as long as you aren't being a huge asshole about it y'know?
>Town guard refuses to budge on allowing the strangers into town with a tied up bandit
This makes sense. The guard has no evidence or reason to believe the bandit is guilty of anything. As far as he knows, these are just some thugs with a guy they assaulted and tied up. I think it'd make sense for the guard to want to be able to more accurately assess the situation.
Unless you're players are very reputable heroes, or there's a good-aligned champion/cleric in the party, pretty much nobody has any reason to trust or believe them in a situation like that.
