Mod Idea
When zoomed in with artillery i've noticed you can always see buildings that are destroyed and trees falling over. If this information is always displayed even if you cant see the area could a mod be made to ping every area an event like this has occurred for a second or so. It isn't a perfect MH but as hacking doesn't work the best in this game this could still give an edge knowing where they are at least some of the time. For instance you would always know what direction the majority of their team is heading to counter them.
Perhaps the origins of shots fired could be pinged as well as they are also always shown
Just a thought, i have no idea how any of this would be done :P
