@beaker007 - is there any way on your land tool to see the total consumption and production of resources by rarity?
I have a theory over 50% of production is coming from the most efficient plots (highly boosted epics and legendary), which use the least amount of inputs....
The boosted plots producing so much more than they consume means that it take a whole lot of "inefficient plots" to absorb the excess production these boosted plots produce....

@azircon - here's an "alternative suggestion" to use more of that 9B grain - if we have grain used as an input for crafting products, it ensures grain is not avoided by the highly efficient grain producers.

However, I would echo beaker's concern that too much demand for early and intermediate resource - could hamstring the "overall" demand for land products as a result of too much cost or risk at the end-product stage.
So my thinking is that grain probably needs to be highly available and affordable, or all further production cycles will stagnate.

There should be SO MANY opportunities to spend aura that no one, (except maybe vugtis), wonders'"how am I going to spend all this aura".
At this time, unless people are spending way more on raffle tickets than they can possibly win, there is simply no way to spend more aura than we are producing. And that's the case where only 30% of land is active - imagine if more was active?

Raffles and auctions are a start but we need lots more like this.

Continuous demand for aura, as the last level of production, it drives all the inputs before it.
