As do many of us, I have alts in all tradeskills and I am happy to say that all of them have the new Shadowscream recipes (even my provisioner thanks to the generosity of Alyxir!).
Gnomi has shadowscream adorns volumes I and III which have the most useful adorns. The alt account has volume II for those that are interested in blocking and such things.
Gnomi has Shadow prospecting tier 7 recipes for armorer, jeweler and weaponsmith. My alt account additionally has tailor and woodworker volumes.
Everyone can pick up the acrylia tack recipes for cheap from guild recipe person and until folks get the better recipes, most of these will be an upgrade. Since they are heirloom, being able to mass produce your own is very useful!
