Since this is about Team Instance I want to add some additional observation. Whenever you use that automatic matching either you or one of your teammates, or both, will almost always get disconnected. Funny since I don't encounter that kind of problem on other battles like Sage, Arena, GNW or Group Convoy/Plunder. We got fed up with it so me and my group buddies just do a manual team creation before entering Team Instances. We didn't get disconnections using that.
