I used to not care about solo queue being removed.
Unless I got with that one 4 man premade that made me totaly change my mind. Riot I beg you listen to your community, we are the one playing the game and I can ensure you that dynamic queue, while a fun concept, is just not what we want. Solo queue still has it's place. No, we do not always want to play with friends.
Dynamic Queue was supposed to be a better version of Teambuilder. It's a worse one.
1- In dynamic queue, you can't chose your role. You chose two and maybe you'll get the one you want.
2- In dynamic queue, you are punished for leaving a team doesn't fit what you want to play with. In teambuilder, you could freely look for another team if you didn't feel like playing with a Kindred ADC or a Evelynn support. In Dynamic queue you can wait up to 30 minutes if you don't want to play with those kind of people.
3- You are also punished if you dodge a 4 man premade that is rude to you from the start.
4- Communication is dead. Teambuilder and solo queue were all about communication, but now communication is just between the premades and the others are left alone.
