I believe that CE events give too many collectables out which people are selling for unrealistically high prices. People have been abusing this since those started happening, I remember people joining the events with several accounts just to get more collectables. Now that we can buy an unlimited amount makes it even worse imo. I've just came back from CE and people are already trying to sell things for 4000% more gold. Yes, 40 times more expensive. People even sell some items from not even a month ago for over 30k, and a lot of them are staff members. That's just crazy considering most of the CE collectables just require you to be there, and pay 200 gold for an item at most. I think this really ruins the economy.
