Throwing my hat in the pile, done with this game till we get Solo Ranked.
Dynamic queue is a mess of varying groups of people. Some games the enemy team is ridiculously coordinated and obviously a premade. And in that same game and you get put in a team where none of the players are working together or coordinated at all. The integrity of ranked is gone. Who cares if you're only a silver level player if you can get carried by your friends to plat. Who cares if you are a strong individual player if your skill is dampened by the coordination of a grouped enemy team? There's no consistency. Game feel random and are so often decided by factors outside of player skill created by dynamic queue that ranked is more frustration than it's worth.
Please, please bring back solo queue, Riot. More than enough people want it, you're kind of shunning your player base by not giving it to them, and it's going to hurt the game in the long run.
