This is a minor suggestion, but I believe it will make the game feel more intuitive.
When you talk to a scout or are directed to an area of the map in game, the map will pan to the area in question then circle it to make the target location more obvious.
I suggest that when a player sends map information in chat, in addition to just opening up the world map and panning there, to circle the target as well. This would streamline the feel of both player and game initiated map information.
