Going back to my thought about credits, which I didn't mention before at all.
It think Winner Event show smth that was a problem for a longer time - credit farming and economy inflation/demurrage. Even I understand now why you did what you did with event crafting costs, I think it won't change a lot. Right now Blackmarket is completely silent on both - discord and game when it comes to anything.
As caetho mention:
Even PGC won't help fix the lack of buyers for that moment on a game. And it's global problem, around whole server. People who used to seek for PGC a lot, now are not able to buy any from others since most of their credit went either on Cozy Winter/Santa Helper sets or event stuff.
People trying to keep up with credits farming but it's taking too much time (up to few hrs to get a amount of credits which would be enough for at least crafting dailies + some extra stuff). @Soma I do think you should consider option of small 'credit events' which would let people get more Treasure Chests or anything that would increase credit for the time when events are not on. Just a small help for new, or veteran players to catch up with new prices (let's be honest, price for old (even new) Gacha sets are increasing as hell and not everyone in this game are able to spend real money for it). If not so, then think how you can improve credit farming for a players who are still gearing up, because even you got one geared character on C:C, most of the people goes for alts who require materials (so you losing another way of getting credits by selling materials). Or as a last option: consider changing tickets, maybe black market limit or smth else than would stop that inflations and let people keep more credits instead of farming them and still getting almost nothing when you compare it to prices. I already did suggestion about it.
Not mention that prices of everything went down as hell and people are still not buying anything.
