If all three (or however many there are) want to run through as fast as possible and everyone is able to do do, that's fine. There's nothing wrong with that as long as everyone sticks together as much as possible and plays as a team. However, when one or two players are left behind with seemingly no regard whatsoever as to their status, it's an issue. It's a selfish, self-centered, 'I don't give a s***t about anyone but me', attitude. I take issue with that and I'm far from the only one. Players are real people. They're not AI's. So treat them like real people, the way you would in real life. That's how I treat others, even in a video game, and I expect to be treated the same way.
