Team builder is fine. Apply the team pick update to blind pick. BLIND PICK IS GARBAGE.
Blind pick is the only place the new team select update is actually viable. People already love team builder, but the timed hecticness of blind pick, without a premade team is just hateful and ruins the game for everyone that encounters a troll.
Replacing blind pick with the semi-structured approach of the new team select fixes the main issues with blind pick. In that, people no longer have to race to call their roles, only to be ignored by the unwilling. As well as giving the opportunity to players under lvl 25 to actually play in a more stable game environment. In stead of the hurried clusterfuck that is Blind Pick.
In summation: NO MORE BLIND PICK. CHANGE THAT SHIT, IF YOU MUST CHANGE SOMETHING.
LEAVE. TEAM BUILDER. COMPLETELY. ALONE.
Ya got it right, there. Just use your new system in a place it belongs, if you absolutely MUST use it.
