I would be fine with them deleting everything. I just thought this would be a fun and creative way to do it, and be a potential way for ATA to profit. And, maybe some players like some of it. I could understand players wanting to keep the anniversary boxes. I just don't want it.
Or how about redoing events? It's not like they're unique anyway Repeat the event to get a chance to finish off old boxes/items, win-win for both sides, no?
