I'm not sure if you've attempted one of those crafts since the expansion hit, but they're very broken it seems. They're more difficult to craft than anything really should be. I've attempted it as a mid-level crafter and it seems literally impossible, so I've asked some "crafting mains" about it and they say these recipes are just not practical to craft and require a crazy amount of buffing to even get a decent chance at completing the craft. Make it difficult through grinding sure, but don't make it inaccessible.

From what I was told, the crafts now require you be specialist, have the FC buff up, be inside your FC to get the buff from the furniture, use current lvl90 HQ food and medication and also be lvl90 with fully pentamelded lvl90 gear. For these level 80 crafts. This should not be how these work, and they are broken.
