What is the data on support as secondary choice?
It seems like players who choose support as their second choice get it much more than whatever they choose as primary. If I choose support as secondary I don't want it every game. If the system detects that you never get the role you choose for primary it should stop giving you secondary. I am not going to choose it as secondary anymore and Im sure a lot of players feel the same way. This actually lowers the number of players willing to support in the queue at any given time.
