Ranked Ideas

Dear Riot Sometimes when i play Lol I got a feeling that I could play better but one or maybe two teammades dont play like I want. I'm silver and I'm fine with this but I have 2 Ideas for the players in Lol. First idea is a new type in ranked games. A 1vs1 Ranked. Sometimes i play 1vs1 against my friends and its funny and the game is just about me. The other idea is a Team Builder ranked. Sometimes I play ranked and some people are feeding because they have too play Supp or Jungle. So with this everyone coud play the role they want ane can set up their Teamcombo.
