Ping Clarity
Alright I don't know if anyone else has thought of it, but I was thinking that when a player uses a regular ping instead of the blue circle on the ground it shows the champion who pinged's face. It would bring some clarification to the game when pinging in the fog of war. Although not game changing the fact that you know who is pinging can help communicate what your team wants to do next. Of course there's chat and all, but there's never a reason to not have more communication :)
