Yeah, that hasn't changed at all, has it? Maybe someday SBMM will be back. I still don't recall CBMM ever doing any favors with the connection of matches.
EDIT: Admittedly, I have been a little bit out of the loop on what matchmaking systems are used for what modes a bit, but they just don't feel any different from each other to me and haven't felt different for a long time. It's like the matchmaking preferences are being skipped for some reason.
