It is more than a little surprising to me that such an at length discussion has emerged from Belladona of all things. If anything is to be adjusted in this herbalism crafting system, herbs are too plentiful and herbalism too easy in comparison to the other crafts, particularly considering the immediate and long-term benefits of picking up herbalism compared to the other crafts. If people are truly this hung up over Belladona, then I would say to remove it from the herb spawn nodes, reduce the number of herb spawn nodes in all wilderness areas across the board,
Herbalism isn't really that 'easy' compared to other crafts. It's still as mind-numbing as the rest and you actually have to move away from your work station to get the ingredients. None of our professions are hard, just simply timesinks. You just find a lot of people swallowing it because it's actually useful and profitable unlike our other professions.
e.g,
Smithing you ping away on a rock for a good half hour, smelt, then spam greatswords or fullplate.
Woodworking you cut trees for a good half hour, saw, and then spam longbows, shields, etc. depending where you're at.
Alchemy you go participate in dungeons you already do or you can do by yourself. I already see plenty of high level clerics hit the ghost temple hard.
Tailoring you buy materials from a vendor and spend a half hour spamming wool shirts.
Leatherworking is possibly the hardest simply because it breaks up so many aspects in different subprofessions of their own that uses different stats but the materials barring high-end stuff (like ancient croc) is not hard to get.
Enchanting I'm not even sure because I don't have a high level wizard yet.
Barring enchanting, does any of those sound harder than herbalism? You can have herb baskets by the bucketful, yes, but you 1.)can get wolf pelt hides by the bucket as well 2.)biff a lot of them during the leveling process. I think you just mean more useful than the other professions and in your mind, that should mean it should get nerfed.
Getting this nerfed is another distinct fear because it was fine as-is, until junk herbs were introduced.
