If you watch the video closely, you will notice as leader of the group begins to speak to the Mon Calamari trooper, a green ring encircles a wide area, and the whole group steps in. This is the first video to expose this little tidbit of information. The ring transports the group into the dialogue instance. This way no other people in the area interrupt the dialogue sequence by jumping up and down like a rabbit on speed, over the NPC who is talking. (You know what I'm talking about, don't lie.) The most extraordinary part about this dialogue instance system is the lack of noticeable transition.
Watch the full video after the break, and let us know: Is the Force with SWTOR group combat or does it fall to the Dark-side?
