In your mouth with the rollbacks
What if you received a great drop from Dark Poeta, completed 12 hours of grinding, completed your xenophon weapon quest, or dinged 50? I would think all of the above would leave a sour taste in your mouth with the rollbacks. Did NCSoft have a choice? I imagine with trillions of Tabula Rasa credits instantly added to the economy there would be no way to track down everything. It was the best choice for Tabula Rasa, but if you lost something you earned legimately during the rollback hours you will be very angry.
