So long as its:

-A separate crafting writ category but not a new profession.

-Uses the basic green recipes, other wise most players are not going to be able to complete them.

-the boxes give furniture plans in the same way, the provisioning writs give recipes, eg, green and blue blueprints as common drops a rare chance to gain purple blueprints. (even then that may cause furniture plan prices to drop due to increased supply, reducing the only real value of doing writs with such expensive materials)

-The boxes give furniture mat surveys, the prices of furniture mats are high since they can only be gathered. A massive increase in demand would make prices soar, without a means of providing a reliable supply via surveys it will defeat the purpose of the idea, to get more people taking part in housing and ultimately make it harder for people who want to make furniture to get their hands on the mats they need.

If they don't provide provide surveys, prices will skyrocket and those that are actually good at gathering the furniture mats, might just hoard their own stockpile to do the writs themselves instead of selling on traders. It would depend on the benefit the writs provide vs the gold they can make selling the mats, (think alchemy mat prices, once every player starts going out and harvesting raw mats, screwing up all those people who run harvesting routes)


that's my 2 cents.

Writ plans need not be the same ones that we currently have. They could be constructed so that the need for the furnishing-only materials is lower, and even that could be mitigated with returns from the writs.

Furnishing material surveys could be a big plus, but I'm not sure how they would work. Perhaps you'd get nodes that yield mostly the furnishing mats and a small proportion of the regular ones, rather than the other way round. So a metal node would give 3 Rubedite ore and 17 Regulus, for example. A survey would have six or seven different nodes, one for each craft?
