I personally think that harvesting nodes should give you a small chance to get these kind of materials. I did some testing, and with 200 Pieces of raw materials i usually get 1 or 2 legendary mats, to gather 200 raw mats it usually takes about an hour or two, Taking in account that gear aside from jewelry doesn't drop in legendary, the amount of gear there is in this game, the cost of those materials thanks to the low drop, and the fact that upgrading equipment from epic to legendary costs 8 legendary mats for each piece of equipment, it becomes almost impossible to upgrade gear without playing 24/7.
It also makes sense, why would you not find resin while cutting wood? why would you not find minerals while you are mining a vein?
