Greetings, I have decided to take the time to compile a list of items that haven't been in the economy for quite a long time now and would be beneficial for them to return sooner or later. This includes variants of items they I don't believe have been released yet.

Notes about promos - It seems that you guys want to mainly run reoccurring boxes + gems this year. So I won't expect any of these boxes to return until next year. However, I think nearly any box aside from gems on this list would be able to generate a lot of hype and make you guys bank. I think it would be very beneficial to run some of these boxes in addition to gems. Many many people are looking for items from these older promos and if they were to return the economy would be a lot more exciting and the community will have more options for costumes.

VERY RARE ITEMS

These are basically all items that are so rare that they deserve to be re-released in some form, preferably on the Supply Depot.
Standard Color shoulder boosters (Fancy, Dusky, Prismatic, Divine, etc) - I have already talked to Cronus about these, but they are still nearly impossible to find due to drop rates. I insist on them being release on Supply Depot.
Prismatic Ankle Boosters - These are one of the few lockbox only prismatics that have not appeared on flash sales yet...
Shadow Extension Cord - This is a one of a kind item that was released on the Auction House. The player who won this item is now permanently banned, meaning no one can get it anymore.
Shadow Devious Horns - Another one of a kind item for seemingly no reason, Gome-Xyz has already spoken to Cronus about these. They should be re-released.
Raider Sets and Raider Horns - You know, the ones that you guys flooded Supply Depot with in 2019, Gome-Xyz has also spoken to Cronus about these, but it does not seem that he wanted to re-release them sadly. No one has really held them from way back then so they practically don't exist unbound.

These are items that I believe exist, but have never been put out into the game's economy.

ADDITIONAL NOTES ABOUT SUPPLY DEPOT

I think many things on this list would benefit from being part of either Flash Sales or Random Depot Sales. Random sales in the past have always resorted to "normal" items such as Leafy Auras, Anti Spikes, Mixmasters, Feathered Auras, Random Prismatics, etc. It would be better if we had less predictable listings that actually got more of the community interested in bidding or buying the items. The sales we had on the anniversary was a good step in the right direction but there is still room for improvement.

Personally, I think listing 1-3 items daily on the Auction House would get the economy and market moving a lot more. They don't have to be high value items either. I would probably list 2 low-medium value items for every high value item.

Thanks for reading this post!
