Dear riot
Riot you did a great job and this is not a QQ thread. So far the largest problem with champ select has been the players not reading the helpful text you provided them with. I'm sorry that your customers are blaming you for their laziness and stupidity. As we continue to use this system and players adjust it WILL stop being an issue.
As for the issues ascribed to combining solo q with premades, ultimately I think these can be taken care of using the recommended players list you've already created. Perhaps the honor system could allow you to be matched with players you've honored to provide a more pleasant climbing experience.
