So with everyone on the fence recently about Energy pricing, promo boxes, and the economy in general. I felt the need to put my two cents in the conversation with an idea myself and a few other members in the community discussed about a week ago at length. I am awful at writing so here goes my best shot.

Essentially the idea is to add a black market sorta style event (similar to how casino functions) that could maybe include a black market auction house, where everything is dealt in energy instead of crowns, and obviously only available while the BM is out.
There could also be an NPC that has a rotating shop, either rotating daily during the event, or per event rotation. This NPC would sell old promo boxes / promo items (depending how this wants to be handled) for again, an energy price.

Reasons for why this would be a good idea:

Energy is currently useless in the modern economy, there is nothing for players to sink mass amounts of energy into, where there is just about every reason to convert it to crowns. I wont go too in depth on this, as a separate forum node was created just yesterday going much more into this topic, I invite those who are unaware to go read up on that.

Old promos / promo items are HIGHLY desirable and many of which have not been available for years, and if im not mistaken, Cleaver has said in a previous forum node that part of the reason for not rereleasing promos is to make room for the new ones, where the community wont complain about new ones. We do ultimately care 1 000 000 times more for the old stuff... especially those that havnt seen the light of day since their initial run. And this would give a way to access those cosmetics / items WITHOUT taking up a promo release slot.

To also go off the above point, any new players getting into the game cause of all the recent updates see old players with all these fancy items, fancy sprite skins, the whole 9 yards, and will NEVER be able to have those items in most cases, from a new player perspective, I can see why alot of people quit and give up on the game. As it currently stands, the entire end game of SK and the entire reason to really play the game, is to build those dream sets players come up with during the intense grind of hitting vanguard, only to be shut down by society and a growingly worse economy and told all their hopes and dreams arnt realistic without spending a ton of real money on the game, or literal thousands of hours, its unreasonable.
Im all for rarity, but not EVERYTHING needs to be rare... again think of yourself as a new player, seeing someone with full BK, a mix master, great UVS, and a killer cosmetic set to go with it - all u wanted to do was be this guy when u were leveling; and you cant! (without actual thousands of hours spent playing or thousands of dollars spent).

At the time of writing this post, Rage Prize Boxes were released on the Supply Depot for players to buy, within 10 minutes haven was full of players all spending their crowns to convert and buy the boxes, within 1 hour the E-Cr rate rose by 2k crs. This is exactly what needs to continue, and proves the E-Cr market needs to have stable currency sinks for both. An economy that can heavily fluctuate and go as low as it recently has (dropped below 2k/100e within the last week) is again, just not fun for anyone, even those new players who love to buy orbs cause again, any items that player will want later down the line get more and more expensive as energy gets more and more useless, and if they dont want to spend hundreds of hours farming, well, now they have to spend hundreds of dollars.

This is all just a general concept to get the conversation flowing on the forums, rather then in and out of the discords for the past week. Id love any and all feedback or input people can come up with revolving around this idea.
