This is in facct the most common and ignorant msitake people makes, Every queue uses its own Elo System wonder why they resetted the win/loss count some patches ago? because Normal Treeline used the Same ELo rating than the Normal Sr queue they resetted it in order to split Treeline Elo (effectively resetting it) and Normal Sr Elo so that youu experienced treeline players didnt get a Random Sr guy trying out a build for normals and not caring about the outcome of the game.
See lol matches for further reference ( a program some of us Used to track our ELos, msotly used by DOminion players tracking their DOminion ELos until riot shut it down, well it still works but Elo no longer updates)
Lol matches last effective ladder the proof of an Elo system on every queue the Rating Widget is the effective Elo+4/-4 The players had a that date
Note that this was before the Reset so treeline and normals still shared ELo.
