Patrol fireteam max size should be increased to 6.
Want to do court of Oryx or Archon's forge, ensuring you have the best chance of victory by having the most players? Well, too bad. You can only have 3 people in your fireteam, if you want any more you need to run into someone at random (okay chance at CoO, horrible chance at AF).
I think the maximum size for patrol fireteams should be increased to 6 so we can easily get the people we need for activities like this.
