Way to tell how far the enemy is

This is mostly a idea for ruins,3v3, and ctf. Im sure everyone knows of the x Icons and the :) icons etc. So what if when these people got closer it would become bigger example:

x

YOU X x :)

Like that so if they were to increase in size people would know when to run etc. Or when to steal the flag. So leave your comments below ABOUT THE TOPIC.
