Seriously, VW loot system..come on.

You summed much of my thoughts up, but you didn't quite reach my conclusion. I think you excluded an option here.

Look at how many people currently don't use stones/cells if they don't want anything from the NM, even if it drops plates or riftdross/cinder. Ticket prices will be dictated by the price of voiddust, cells, and the rarity/demand of the item the ticket represents. Given that no Voidwatch item is powerful enough to drive price significantly above the sum price of the input items (in a perverse way you might even argue they're worth less), many will simply choose to forgo seeking tickets from a NM if they're low on stones (thus driven to use voiddust) and already have their desired drops. In other words, this doesn't even add enough incentive to use stones to justify its implementation. That's how bad this system is. It will barely (maybe) be worthwhile if you get a ticket for something you have and can sell said ticket for and you can also gain something else of value from the same NM.
