The bigger question is:
You're paying us in diamonds for our help in beta. If we can't use them to study the events, do you think beta people are going to spend cash to do that?
In my professional career, neither I nor my company ever asked to said to customers that helped us shake out beta products, for any money. Conversely, I was never asked by Microsoft or Google or ANY other company that had me helping them do beta - to spend money for Windows beta, or Office beta, or anything.
Yes, there are people playing beta that are playing it as their live game. Many people are. But many people are actively helping you study your beta products, and it sounds like you're saying we have to spend money to be a legitimate part of this testing environment.
You really should rethink that for those here spending time to help you.
