'Tagg a friend' update

I have noticed that even after the 'Tagg a friend' update the enemies unit was the same highlight as before and is still as unidentifiable when the map is zoomed out because they don't stick out like a sore thumb unless I squint at my screen.In all honesty I was expecting the highlight units be like the ones shown in the update image where they have 4 distinct colours which can be seen amidst many other units with different relations as well as your own.
