???Why isn't Showdown a readily available game mode????

I honestly don't understand why? we have 3v3, and 5v5, why not 1v1 and/or 2v2?

People are playing 1v1 modes anyway. and you already have a map for it. It would literally take no time at all to add to the game and its just another playable option so its not taking anything from the game. We aren't even seeing it in the rotation either. Adding a competitive 1v1 and 2v2 mode will only be a win for everyone. Worst case scenario would be that people don't play it but even if 5 players play it, thats 5 more happy players.
