Some younger kids are fine to play with, it's the ones that talk and talk and talk and talk and talk constantly about the weapons they have the ones they want and other things that I don't want to spend a whole raid talking about. That alone is enough to make me want to leave regardless of this persons skill, I'll usually stay because I'm a nice guy. On the other hand I've played with young kids that will talk about other stuff, call out enemies and take care of business. Not everyone is a dick, my advice keep the conversation on the task.
