I’ll jump in on the other end and say that this sort of feature shouldn’t be implemented at all. While interacting with retainers and stuff with the Scenario Engine sounds nice, I’d personally like to see time spent improving other facets of the bot instead of adding something that A) Kills the in-game market over time and B) can look awfully suspicious if you are consistently updating your prices at set intervals. While a “cooldown” could solve this problem, even with a random one, what is the point? If you make an item that is worth buying, it will sell. If you’re really that strapped for cash then undercut on your own.
I don’t see much of a point to it.
