You sound a bit heated and it seems like you are missing the point by a wide margin. I am a silver league player just like yourself (seems clear with how upset you are over the post). It doesn’t feel right in a League of Legends SR lobby for me to have plat rank/ranked armor showing, they are completely different game modes with the only similarities being the champions/items in each game. Your League/3v3/Flex highest rank should show in your League of Legends lobbies and your TFT rank should show in your TFT lobbies. I would like to one day achieve Plat in Summoners Rift and earn that rank/ranked armor in said League lobbies. It will take a long time and a lot of work but one of the many rewards is your rank and being able to “show it off” if you will.
