If you don't want dynamic queue don't play it.
Riot has said that as long as dynamic queue is getting played and is functional that they will not release soloq.
There is an easy solution to get soloq back.
Don't play dynamic queue.
If the whole community says "Hey Riot, we really don't want/like dynamic queue so we will play every game mode EXCEPT dynamic queue". Then Riot will be forced to either remove dynamic queue or drastically change it from what it is right now. Yes I know that would mean no ranked for a while but if the community would unite and do this then maybe Riot would realize how far the community is willing to go to make our voices heard to the extent that WE want Riot to realize, not just their "sample poll" opinion.
