I was thinking more of NPC only missions showing in the HUD. Not sure it's feasible, was just a brain storm. I was thinking of the paper trail involved with multiple toons to keep track of who did what NPC mission.
Just an idea and I'm not sure it's been mentioned before, but I think it would be neat if I could target a base and the HUD tells me if there are missions available from that base. No missions, no HUD message.
