I hazard to get involved with this conversion, however ...
If some of the long time customers were consistently earning significant credits due to their jobs at Super 6 conferences, I doubt that the powers that be at WIS would be all that concerned about their potential exodus from the system. Potentially, WIS believes that that they were not making money off of you (those who were earning significant credits due to Super 6 jobs) with the previous system, so why continue to sustain a dying business model. If new users do not feel that they can make progress in the game given that recruiting was stacked against users who were not in power conferences with massive recruiting $$$, they are less willing to invest into the system. Granted, their current model may or may not work, but it's far too early to tell. Given the number of people who are cashing out their credits, WIS may be pleased that you won't continue to accumulate credits because there are other users who will want your Super 6 jobs who are paying into the system.
Furthermore, with the bitterness and vitriol on the board, I'm sure that most of you want the process to fail quickly. However, there should be some attempt to understand why they decided to change the game instead of the constant hateful threads that have become commonplace on the board. If you want to ruin the game for people who actually enjoy it and are open to the changes, it says a lot more about how you are as a person than how WIS is as a company.
