Is Roll Queue a valuable system or a mistake?

I've been playing this game since release and I've seen pretty much every terrible comp imaginable. I think role queue is fantastic for the competitive scene, ever since it released I've experienced an increase in game quality. I'm willing to deal with increased queue times for that. However, I don't think they should have forced it into QP as well. QP is barely a step up from arcade, and I think people should still be allowed to do what they want.
