I have seen these party's pop up lately and on stuff like Sophia/zurvon ex which unless you get incredibly lucky your not going to get 8 birds so the parties sit up up at 6/8 for like 50 minutes because no one is going to join the last 2 spots.

Also had a group on Sophia ex try to sneak it in after the group filled up 5/8 were on the same server but they tried to act like they didn't know each other and act like they just decided this was the best way to farm it.

I just cant understand why does joining a party first give you more priority then someone else this makes 0 sense and is just the leader of the party trying to insure they get their drop.
