TFT Game Suggestion
I think a cool unique idea within Team Fight Tactics would be the ability to queue up with another friend and control one single player. To clarify, you would queue together and the game would be different because both players could handle the deck and the playing field.
I think it could be an interesting concept for ranked 2v2 games. Create a tea, similar to how Twisted Treeline works. Talk in League Voice, Discord, etc.
May be difficult to make it work, but I thought I should throw the idea out there.
