New role idea: commander/shotcaller
The basic idea is that there's a 6th role for someone who's job would be to specifically help and communicate to your team to win games with less biased macro calls and ideas/strategies.
How it works: i dont believe this should just be another role you can choose in solo/duo (because everyone would use this to rank up and then try to play their role at an elo they arent competitive in) but rather a seperate queue with its own ladder. It would be its own placement and ladder away from your solo/duo mmr but would be attached to soloQ games. For example, lets say you get placed in silver for this you start a seperate queue to play this role and it would match you with a team of soloQ silver players. As your commander/shotcaller rank increases you get placed to help teams of the same mmr in soloQ as your commander/shotcaller mmr.
Reason: many people are very smart but have little to no macro knowledge, and this should be rewarded. I also believe with soon time that it would improve quality of games and help players grow/learn faster. This idea is a wip but i thought id like to share it and see what others think.
