Never got this about ranked Queues...
When you just hit 30,you are paired with some average league players and if its your first time you aren't going to win (unless its a smurf).
When you are winning and moving up out of your tier, you get paired against some guys in the above tier,who are likely to beat you,keeping you in your current tier. Saying that you should beat that higher ranked guy is like assuming they are equal or lower than you,and of course carry your team.
when you are losing,you are paired with kids people of the tier below, saying that while you should be able to own them,you should have to carry a tier of this lower rank,while at the same time beating a team "that should be able to beat yours".
lets look at this now. If im ranking up,and im paired againt someone who is moving down, who should win? What if i had a few good/bad games and got my mmr like that? does matchmaking state that we are now equal?
I don't get it.
