Why is it that you HAVE to pick two roles to fill when going into solo queue? Can we not just opt to wait longer for the role we want? I really don't want to play anything but my main role and having to wait 5+ minutes for a queue in the first place, I don't mind sitting the extra time so I can secure my main role. Whats the point in making people play something they don't want to play? They picked a main role for a reason.
