I understand that, but it is no different than moving from 'semi pro' to 'pro' in any other sport. When you decide to make the move, you leave your 'semi pro' rank behind. If you decide 'pro' is not for you, you can delete those subs and move back to 'semi pro'.
I just don't see what the problem is with that. The people who are really hooked on OC competition will stay no matter what.
They can't have their cake and eat it too. Just my opinion, take it for what it's worth.
EDIT- Myself as an example. I have very few sub ambient subs. I am in Extreme. If I delete those subs, I could very well be in the top 40 Enthusiast rank. Does it matter?, no. I know what my skills are and don't need to be rewarded to stay in the Extreme league.
