If this is such a big deal, have one of the Open Class Corps Directors put a motion in the winter meetings for this to occur next year. If no Open Class Director puts in a motion, you have your answer. It might be the fans choice, but not the directors choice. Or conversely, there should be a strong lobby effort that is on=-going with Dan Acheson - BUT the support of the Open Class Corps is critical.
Personally, I have mixed feelings. Why should an OC corps reap the benefits or participating in a WC event, when they knew the ground rules going in. On the other hand, if there was no direct financial benefit to the OC corps, then I say set some criteria, let them go on first, and let the cards fall where they may.
