Players New To Ranked Shouldn't Start in High Bronze / Low Silver
They should start at the bottom of Bronze.
If Riot wants their game fixed without increasing game times again, here's a place to start.
The discrepancy between players new to ranked and even Silver is too high.
Let them start off lower and climb faster if they win and stay down there if they don't.
If good players using smurf accounts is a concern, then do something about smurfing instead. With the way League is set up right now, those new players are going to cause one-sided stomps anyways.
