I see a lot of concerns here and I'll try to address them all. But, before I start, please keep in mind that these ideas are not always or not done by one member of the GM team, so I might not be able to provide all the answers you are looking for right away.
People have complained in the past that the Fairy Auction gears weren't enough, and they have been gradually bumped up, mostly the gears that you see have already been sold once or twice....
Currently I don't know the droprate of the Love Flower Hat, but will see what we can find out about it's %. This is the 2nd time this hat has been sold in a Fairy Auction.
For this auction there is 1 new item to be sold, that has -never- been sold or offered before. Everything else has been offered, but possibly not at the Refine or + Addition..
The refines are mimics of ones previously sold and sometimes they are +1 higher than the previous years, or sometimes they are added to a lower headgear, but this only speaks for some of the packs that are present in this thread.
About the Backpack - Since it is a diceroll it's up to chance if they are going to even get the +3 Stat or if they'll get one of the other mentioned items. Yes, there is a possibility that they will get the +3 stat, and if you see there's also a possibility of them getting nothing more than the backpack
As this is already posted, current items will not be withdrawn from the sale, however I will be sure to speak to the GM team about the sudden concerns with the enhancements and we will take it seriously for all future Fairy Auctions. We apologize if that makes anyone unhappy.
