I would like to see a feature added where logged out characters can be seen sitting or standing arund at their fleet starbase? I would love to have my Admiral sitting either in the confrence room, or across from the couselor when I am not activly using that character. It would also be nice for the player to set what his/her character says when approaced by another player.
Or have it randomized NPCs from the fleet. In order to show all 500 of a big fleet, the NPCs walk around, walk to the transporter room and beam off, then another beams in. That way, you wouldn't have too many NPCs out and about.
Or, alternatively, have Tacs on the Tac level, Sci on the Sci level, Engis on the Engineering level, and fleet leaders or random fleet mates on Ops.
I could see the team prioritizing those NPCs. Like Leaders and Senior Officers sitting in the Conference Room, Junior Officers sitting in the lounge area, and the lower ranked members dancing or wandering around performing tasks.
