The problem is those people hiding in Open who can still influence my Solo game!No, the problem as OP clearly explains is that people who don't play in Open still influence Open. What you make of that is up you you, but willfully misrepresenting a very simple argument just to make you feel better about the mode you chose in a computer game is rather lame.
The problem isn't that people can't see you. The problem is that they can still smell you.
The problem is those people who think they have a right to tell me (and others) how to play!
