Just abolish the rating system and replace it with a certification system = no more C3 debate.
Kidding aside, for me the rating is just a rating, it serves no valid significance that will grant you access to anything special. Like previously said, there's really nothing a C3 can access that a C1 cannot. If we're talking about seniority, or perhaps, those who goes above and beyond the expectations, I know a lot of C1, even S3 (that I also happen to respect a LOT). It doesn't have to be a C3 guy walking around to earn someone's respect. It's how you demonstrate yourself to others, not by rating, or "experience" alone. As long as we're all enjoying the hobby while giving back one way or the other, it's all that matters.
One could really give all his/her efforts, not for the genuine intent to actually 'give back', but for a certain rating. At the end of the day, when you don't get what you were expecting, it will only leave you disappointed.
My 2c for what it's worth..
