I just was excited about the new teambuilder replacement and found a very annoying flaw of it.
I Play pre-made bot with a friend,
i cannot Queue up with my team-mate. Several tries we were not able to Play botlane together.
So we decided to use blind-pick, the problem is, other pre-made bots Spams "premade bot" or they leave the queue when we say bot first.
Please Change this!, i want to Play with my team-mate in one lane!
We ended up playing Coop-Vs-AI.
no thanks to this new teambuilder that forces Player to roles they dont want to play.
