You have some god points, Deep Terror, I wouldn't mind trading champs and roles if the situation was more "need-be" and I was playing with friends.
That being said, I usually only get two hours to play league on weekends and Wednesday, and even that is too much playing but its all I have. Team builders was the fastest way to get into a game and the developers took that away from us. And I don't wanna spend 20 something minutes in a lobby. Some of us know what role we want to play. Plus, I don't want to play with new players, which is about half of the draft and blind pick community is. Plus, the annoying two out of three of the lobby ques disband because someone didn't make a pick or ban.
I'm sorry but Hotdog is right. Riot just reduced the game and made it unpleasant for me to play.
