Hey guys, we know there are a lot of players who are really passionate about solo queue. We're not trying to be dishonest or dodge this >topic. Radio silence on this the past couple months has been painful, we know. We hoped to come out with a direct answer to this, but >working through the problems players are facing on live now (consistency around position select, queue times and matchmaking for high >MMR) is taking longer than we initially expected. We did a bad job at managing expectations around this and deserve the heat we're >getting around that.
That being said, solo queue does not directly address either of these problems and could suffer from the exact same problems. We'll be >honest: there's definitely a world in which solo queue doesn't return, but we'd rather keep it on the table as we work through these >issues before making a final decision.
This is the post I am referring to. I think it is the seed that is riot backtracking on solo que.
