You assume a lot. And i'd guess most is incorrect. They offered the people from Beta a one-chance deal to transfer gems to the live server. I'm sure it is more of an accounting issue than one you 'assume'. Once gems/monies transferred, they were no longer available, but allowed to play on Beta if they wished. Honestly, not much has actually been tested, and what was was for a short time before release. They just don't delete anything, so there it is.
