Eh, I like the new champ select and think it could use some improvements. DQ is shit though. I'm normally not so blunt, but it's bad. DQ not only ruins the competitive environment by putting group with solo players togrther, but it has also actively discouraged me from playing with my friends.
Before DQ, I had a group of friends I played with on a ranked team. Our skill levels varied highly, so the ranked team gave us a way to play together competitively while being able to objectively see if we were improving as a team or not. Now I can't even play ranked with half of them, while the ohers I'm afraid of playing with because I don't want to ruin their rating or my own rating that I've worked hard for.
The premise of groups playing competitively with solo players is horrible :/.
Quick edit: Forgot to add, I'm plat, I've been plat every seasonsince S3, I hit D5 in S4 though I got demoted cause I don't believe I belonged there.
