I wouldn't call this an update. It's just the same old currency event like all of the other one's rehashed in a slightly different way. An update is something that adds meaningful stuff to the game like the quest point shop for example. Thanks for the currency event but I wouldn't consider this an update.
Everyone should just be grateful they don't get banned for not buying the products. If they wanted to they can easily ban us for not buying treasure hunter keys yet they don't we don't realize how lucky we are.
