I normally vote down threads that directly address Riot, but removing this feature in the recent update was a mistake.
Now, the shortened timers on PBE right now are a very positive change, but not pinging people where they have an action to take during selection is still a problem.
I don't play ranked anymore, so accidental dodges don't really affect me. A 6 min penalty for dodging because I was reading a website while players take 30 secs each to ban a champion in a bronze/silver level Norms game isn't the end of the world.
Taking the full 700 secs for selection norms is like drawing out a 4/8 limit game in poker. Make a decision and move. It's no limit WOSP play.
Edit: No design decision is going to make me care about what players are saying if they choose a double adc bot lane or a thresh jungle. I just want to get in game as quickly as possible. Either people build a decent comp or the game ends at 20 and you move on. No amount of selection talk is going to fix the dumb team comp stuff.
