I had an idea that I though would be useful to have. Ally and enemy ward should list the name of the player that placed that ward. That way people can know who placed what wards around the map. May help avoid confusion when maybe an ally asks if you have wards left, or you know that its your allies ward, so you don't need to waste one of your wards to place it around the area.
Let me know if you think it's a good idea. Thanks for reading.
