I might be able to help. First keep in mind each Que has its own MMR.
Next up.

Now then lets look at riots Matchmaking priority's.
"The basic priorities of the system are (in respective order):
Protect new players <-----------------
Create fair and competitive matches
Make games less toxic by matching you with the right players."
That's right, its a higher priority to prevent newbies being abused, so unranked or not if your MMR is high in normal expect to get placed with other players with high mmr. You can smurf to abuse folks or que up with smurf/bad players to abuse folks, but that's so unfun for players who are less skilled that Matchmaking will occasionally make lopsided games in its attempts to prevent it, and odds are if your one of the people being/looking abusive you run a higher chance for it to throw you to the wolfs. You wanna play with your skill range? don't smurf, play lots of ranked. You wanna play in competitive environment with hommies? Make a team, play ranked. You wanna smurf and destroy new players or lower elos? have at.... just don't get mad when MMR pushes back.
