I started crafting tonight. It's... Incredibly simple compared to launch Heavensward crafting. There are easy leves that don't require tons of materials, the new skills and traits are actually useful, the class quests provide you with the crafting materials (they function like the Moogle dailies, so no more farming), and you get a ton of experience for completing them (seriously, do them, they're like 2 million xp).
My only complaints are that they put zero effort in redesigning the awful Heavensward skills and just left them as they were, and the whole system would have benefited from some pruning, the skill bloat is real.
I'm not 70 yet but so far I'm really pleased, as 3.0 crafting was a lot of suffering on top of suffering.
