while on the Citadel? Fantastic idea.

Making that map extremely vague? Horrible idea.

Honestly I think I've spent more time searching for people that are supposed to be by a certain area and end up being across the map than anything else. Would it have really been so bad to simply show the player the specific spot on the map the character is?

Yeah... running around each area looking for interactive circles is not the strongest aspect of ME.
