It would be a little bit useful for single player, but really useful for multiplayer where we can see our teammates’ character appearing and not moving, not knowing if they started the zone transition or are waiting for us, etc. A small loading icon beside their character/portrait indicating the teammate is still loading would help synchronize group play.
Also, adding player status that they can set (back in 2 minutes, etc.) when they get a call, etc. so we know they should be defended, and maybe a status telling when they are focused out from their LE window automatically. It would help when party members need to take a call, etc.
