Im pretty much Herb Alch for life because I like not having to rely on anyone else for my consumables. The addition of Sky Golem completely changed herbalism for me. All professions are represented with the 11 warfront quest and I can promise you if you know how to play the AH a little you can make a fortune off the items required for turn in. That also being said, profs were not a big focal point for me on my months of beta testing. I went herb alch on the first pre-made character just so I could have consumables for Raid and M+ testing.
5% was admittedly an exaggeration, just felt that low. I'd say it was probably closer to the 30-40% range. It was Artifacts of the Blacksilt, spent a good 10-15 minutes killing Blacksilt Seers to get two damn idols to drop. A quest that had me killing Elder Brown Bears for bear flanks also took quite a while, though that was less due to drop rate and more due to how spread out they were.
There are professions you can train in to make money in the game. You can be an herbalist to pick useful plants; an alchemist to make potions; a miner to mine ore; a blacksmith to craft armor; a jewelcrafter, who can cut gems that can be socketed into certain items to augment them; or an enchanter, who can enchant items to have bonus stats or effects.

Azeroth Auto Pilot est un formidable addon pour ceux qui veulent juste voir leur phase de pexing réduit au minimum et ont un intérêt minimal à lire les textes et regarder les cinématiques. De nombreux retours ont été faits aux développeurs au cours de sa création, et après avoir utilisé l'addon du côté de la Horde et de l'Alliance, nous pouvons désormais fortement vous en recommander l'utilisation.
Fish, meanwhile, were significantly devalued by the Underlight Angler, an artifact-quality Legion fishing pole that made fishing so productive that a very small number of fishermen could supply an entire server with materials for cooking. At current rates, fishing in Battle for Azeroth is more time-consuming, which means less food to go around, and higher prices at the auction house. Of course, Blizzard could change spawn rates in a future patch, but as of now, signs point to an economy in which common necessities will be much more scarce.
Something to keep in mind as well is that this will make enchanting materials more valuable, since it is likely most players will now simply scrap their boe greens instead of getting them disenchanted. Also redundant dungeon/raid gear can be scrapped rather than traded to the (guild) enchanter in the run. Less stuff gets disenchanted, meaning there will be less ecnhanting materials, meaning their value will rise. All the more reason to DE rather than scrap as an ecnhanter.
