Hey hey, we are talking about episode releases, that’s a total different topic and the “fast progressive” never was intended for your specific inquiry.
Though there has been adjustments from common zeny farming loots from 50-60% selling price to 30%, it is pretty common for a server to make changes to the said item list. Untradable badges is not considered a nerf, as officially it has never been tradable and will never be tradable in the server. However, all items purchased via badges will be tradable, such as consumables, quest items, tickets, etc. Again, those 2 things are common not unless, all servers you encountered in the past never (not even minimally) controlled zeny farming, common ahk/bot farming area and that they all have tradable badges. If so, i understand where you are coming from as it has become generic features for you.
Anubis EXP is more like a feature fix not a nerf. At that particular time, I did reduce the exp from Anubis as I had to rewrite script of one broken feature and I didn’t want to wait for a server maintenance to apply those changes. However, the fix has been issued and the exp had been reverted back to normal no longer than 7 hrs.
Loots that can be traded for tickets have a lesser drop rate. Yes, you are right I nerfed it.
