Chill out. It's only because of the Elevator Pass sale going on. Anyone who has it essentially has unlimited Clockworks access, and therefore can use saved Mist instead of CE for Danger Rooms, Energy Gates, Revives, and Crafting.
Once everyone who bought a pass expires and the pass is removed from the store, CE prices will stabilize. Just be patient until then.
Completely off-topic: I've gotten a few iron lockboxes from FSC runs today. I'm not willing to spend the 750CE it takes to open them, so I was wondering if anyone as of yet knows exactly what they contain, and if they're worth anything on the market.
Maybe the pass will never be removed, and there will be infinite inflation :D
... but seriously, another CE thread? Why don't people make threads about the price of Divine Avenger recipes?? I think those are pretty disturbing.
