Competetive Gamemodes

Yoo Guys.

I'm still mad about the removal of Twisted Treeline. I just don't understand why it had to be removed. So are there any plans on releasing a new competetiv Gamemode other than SR? Sometimes I just want to play a quick (~20min) ranked game. That's not gonna happen on SR. I can't even try new builds without getting flamed when I play SR. So now I have to decide. Do I want a quick game with a random champion or do I want a long (and salty..) game where I can play the champion that I want? Why can't we have a quick competetive gamemode, where we can actually decide which champ we wanna play? I'm not saying that SR is bad, but even the greatest gamemodes get boring and repetetive at some point when there are no alternatives. So now im curious. What are your thoughts? I can't be the only one who wants a competetive gamemode other than SR.
