Why is the matchmaking so messed up?

I don't disagree.  Truly fair is a free for all in my opinion, if we're all playing the same game, the best rise to the top.  Different platforms mixing, control methods mixing, and the forming of teams muddy the waters of fair so I can see the justification for some SBMM. 

But the level of of SBMM has been pretty much what you described up until the last week, and that was fine.  Ranked felt like a non stop sweat fest once ranked up, and pubs was much more varied.  Rarely did I ever run into truly new players.  Now with the new system, pubs is a non-stop sweat fest just like ranked is, so my question at the start of this thread remains.
