I am recently returned to ESO. I went ESO+ because of all the love given to crafting, and have no complaints.
That being said I have an idea of how to take the awesome that has been added and go a step further. I am not certain if it's a good one, so I am sharing it with the community for feedback/poking holes. To get more people involved in crafting and increase interest in completing the new master writs, add something that is tangible return on spending their skill points and time crafting that non crafters cannot get.
On completion of a master writ there is a chance to drop a fragment of forbidden knowledge. Each crafting line has their own. The drop percentage should be somewhere between 1% base and 5% depending on their "crafting completeness" level same as for the master writ percentage. The drop percentage would also increase based on the number of vouchers returned by the writ up to 5% additional chance for a 300+ voucher writ. These fragments are bound to character, as are the created recipes, and the items they create. The recipes would appear in the patterns or housing crafting section for each of the crafts once known.
10 or so fragments of forbidden knowledge combine to form one of the soul crafting recipes for the craft line.
These items allow us crafters to more literally pour our souls into the item we create for ourselves to use.

Optional: Run speed and cheese head effects include a voice over from sheogorath:

"Now where did my rat go. Don't move that cheese!" or something of the like.
Anyhow something like this I think would give a benefit to crafters, increase interest in crafting and provide an interesting goal for doing the master writs. Completing each one should probably add an achievement as well.
