Please make this change for Season 10.
The Leaderboard is very deceiving. It only shows Solo placement on the ladder but you have the ability to Duo, so what does that placement you have actually mean? It means you could have been boosted or had an advantage by grouping with another player.
Ranked Flex already exists for queuing up with a group so why not make Ranked Solo just that, a Solo Queue.
Then we can actually see who is the best Solo player.
