I've never heard of a game that penalizes players for missing a party invite until today. Some queues I've been waiting in lasted hours before I got the chime that a party was formed, but it's a real smack in the teeth when you've waited hours and need to go use the bathroom or get a drink and come back to find not only did you miss the invite but you can't even queue for another 30 mins! It's a bit too much SE, the game is punishing enough without you enforcing some rule against not staring at your screen every single second you're queued for a duty.
