New Ping Mechanic
Recently I played a game of Planetary Annihilation and when someone pings an ally can hover over the ping notification to see what is happening in a small box where his cursor is.
I think this mechanic should be implemented albeit in a different form. What I believe should be added is a sort of ping location keybinding. A specific button can be pressed and the camera will be centered on the location of the last ping.
When used with space for returning the camera to your champion it would make overall vision and teamwork much more effective especially at low elo where communication is generally lacking.
