“5 wins or 15 loses/ties”. If you go through all of that, you get at least 20 matches to get your rank for a single role: 60 matches in total for all 3. Sometimes I think (and some others will do) throwing the match in order to get it faster and start climbing the ladder again, which becomes tedious after a while.

What is the purpose of the current number of matches? I think it should be 10 matches in total to get your rank, making it more dynamic. Is there a con to decrease the amount of time you need to invest on this aspect of the game?
