New Game Mode Suggestion- Reverse Fog of War
A game mode where the fog of war visibiliy is reversed. Knowing where your enemies are and what they are doing over then your own allies. As we all know, "keep your friends close, and your enemies closer."
With wards, they would work under the same function they do now, increase visibility for your team. Functionally/mechanically, the ward would increase the vision of the enemy and because the mode would reverse the fog of war, that adds a benefit to your team.
