So here's your answer as to why SoloQ isn't out yet.

Here's the rundown: We know that for some players, dynamic queue undermines individual recognition of skill, and that’s not something we can solve with iterative improvements. It’s a philosophical difference. But, we know a lot of things that can be solved with iterative improvements, and our current top three priorities are improving the solo player experience against premades, lowering queue times, and smoothing out role selection weight. In an ideal (and optimistic) world, getting these numbers right would make a second queue unnecessary, but it’s not something we’re dismissing as of yet. Right now we're prioritizing the stability and health of a single queue - two would split the ranked player base and have a significant impact on wait times - and this is not a decision we’re taking lightly.

This means they want to make DynamicQ better and if it won't succeed, they'll propably implement SoloQ.

Now stop asking for SoloQ cuz it's not coming before DynamicQ gets it's changes implemented. You got your answer and it's not changing obviously. I'm not siding with anyone, just stating a fact.
