Ranked match making makes no sense.

I've been doing ok on ranked getting up to gold level 2. I've been gathering players who play objectively like I do so we win now all of a sudden a few strange things are happening.

  1. I'm gold, I'm being put in bronze lobbies. I understand if you think I've had a bad game try me in a lobby against silver but bronze?

  2. It seems to be me, a PlayStation player vs all PC players.

  3. When I try and do my usual trick of gathering a gang from people I previously played with in won't let me see in the social section who I recently played with.

This isn't a one off, I was playing against gold players and doing quite well, now I'm against bronze PC players and they are thrashing me on some games.

I'm hoping another random change happens and I'm back to facing people on gold and I'm in good teams again.
