Please Riot listen to the pros
I used to think Riot loved the upper 1% who played this game more than the rest of the community. Being a low elo scrub my 6 year League life I finally see how wrong I was. I thought the introduction of master tier was dumb because only a small portion of the population would ever reach it. I now see why the introduction of Master tier was important and I am happy Riot did it.
Please Riot. Listen to the pros, the community, basically your hardcore and veteran players. You need a competitive ladder and Dynamic Queue is not delivering that. If you really want to keep this game around for years to come and have it become like a sport then you need to keep it competitive. Admit your mistakes and just re-implement solo/duo queue. We will forgive you for experimenting. You could spend your time focusing on bringing new champ select into solo/duo queue. I am sure that would be well received by the community, as most of us like new champ select. You could then focus on making new champ select better, i.e getting players their preferred roles more often, etc. But you have to re-implement solo queue before it is too late!
Don't just do it for me, but for the players at the top who are being screwed over the most by dynamic queue. They are your most hardcore players and their endorsement of your game is very important for keeping the game popular for years to come.
