Prediction for the results of adding 10 supports to the free rotation
I'm sorry, there seems to be an issue with the return function on the boards. Queue times: Unchanged. Winrate of the added supports: Lowered. Play rate of ARAM-only accounts: Lowered. Despite the obvious reason being that Support is just not a fun role to play for most, it's odd they came to the hypothesis that people don't own supports. If they really want to lower queue times, then they should test the outcome of adding an option to Fill everywhere except Support. Plenty of players have voiced that they'd like to fill as long as it doesn't mean being nearly forced into the one role that is most unlike the others.
