Play stupid games, win stupid prizes.
People like you who rage quit and/or dashboard while you're the host ruin the game for everyone else. It's a bit ironic that you don't want your game experience ruined and yet when you rage quit and dashboard, you ruin the game experience for everyone else.
Besides, you're whining right now about something, so are you talking about yourself in your post?
No one is forcing you to do anything. You can quit at any point, just be prepared for a timeout.
