I'm currently sitting at Drybone waiting for my party to finish because some other guy snuck in and stole my spot. I understand why SE would want to limit the number of people involved in the Caravan protection, but I don't see why there can't be more than one Caravan going at a time. It's too easy for a party of 8 to hog the activity, but they get picked apart by random players who sign up before the whole party gets teleported back. If we had 2 caravans, (1 every 10 minutes), or 3 caravans (1 every 15) we would not have to compete for entry.
