"This isn't just a normal chance machine- its a potato sink so people can stop hoarding massive amounts of currency and inflating hard to obtain items insanely high."

If prices are always increased to account for inflation, then these will become those hard to obtain items.

Personally, I find cheaper and constant sinks to be better. I mean, how much did Nico pull out of the economy, for being a good source of cheap alchemy fodder? And how much more could they pull out with increased stock of those items?
