List IV: - There should be a way to intentionally stop a concentration spell, such as fog cloud, without having to cast another concentration spell. - There needs to be a better explanation of the rules. I can imagine someone who doesn't know the 5e rulebook failing to get through the "tutorial" portion of the game. - If your party is already full and you ask another character to join, you should have the option to remove someone there and then. I shouldn't have to go to camp and ask someone to leave first.
