One suggestion: Ping the map

[Rigel]

Just a small suggestion, We had it in previous versions of Civ, but not Civ V. Please bring back the ability to ping the map. It helps dramatically when playing Multiplayer online. Thanks and Good Luck to the dev's, I hope I enjoy VI as much as I have V.

Yeah pinging and showing your allies part of your visual would be nice too. ( like allowing them to see what a certain unit sees, or allow your ally to see what your cities can see and etc,)
This will make teamwork more efficent since your ally can just take a glance and know what you guys are dealing with right away, instead of constantly having to ask your ally if they need help and ask them to describe the situation.
