I know that no one there loves Twisted Treeline.
But, you should probably know that you cannot play a game of Blind Pick on that map without having at least one bot script on your team. This is not an exaggeration, a flame on players or just salt, it is every game. You will be able to identify them easily because in champ select they will both lock in simultaneously and never speak. They will then run forward in lane auto attacking until they die, switch lanes, and repeat.
On top of that, you will have to dodge to save yourself 20-25 minutes of waiting to lose. So since this happens in every queue, it is now unplayable. It has been like this for months, if not longer. I took a break from the game and came back to see nothing had changed. Feel free to log in and play solo. Just try, it will happen to you too.
I don't know what can be done, but I thought you should know.
