Role Popularity
Could Riot implement a system where players can see what percent of players are picking each role? If a system was implemented players could see that, > Top: 21% of players are picking > Jungle: 19% of players are picking > Mid: 33% of players are picking > Bot: 16% of players are picking > Support: 11% of players are picking
With a system that showed us this inside the client, players could adjust their role picks to find a game sooner.
