I think you are referencing the " freeroam" with the triangle in the middle. Thats sidequest stuff. Look closer at the story mission icons. Some have a star with ( ) branch type things and some are just a star. We are trying to figure out the difference between those.

Yes I know. They are story missions but they don't follow the main story arc.

I dunno. As I said earlier, these missions are identical to the beta, same plot/events/enemies,/locations everything is the same as it was a few months ago and the icons were difficult.And " the last array" is pretty important and only has a star. The dark within was the ONLY one with stars and branches during the beta, so the change has to signify something. My guess is something to do with average ranking/score of everybody playing. I wss going to guess mission length, but that is iidentical as well.
