Sure that's true, you can grab some nice high level herbs.. you can fly around the spawning spots and pick what you find, or you can pick in the high level instances when the last boss is down. But still even if you farm a good crop, you'll still have a hard time moving your merchandise at a consistent speed while retaining a decent profit.

Sure, you can create potions and end up with a product that is worth less than the materials you used to make it, and try to move that. You could even get lucky and get one for free depending on your alchemy mastery.

But at the end of the day, chances are you'll have put a lot of time and effort into a profession that could have been better spent doing something else. After all, Blizzard has handed Alchemy it's coat and sent it halfway out the door already and herbalists are doomed to feel the effect of this.

Anyway, on the bright side at least it's not as boring and tedious as fishing, and you'll always make some amount of profit, however little. Plus, people are always grateful when you give them some potions you made from your herb stock, and you could be making a big difference in your group. And let's not forget the direct benefits of herbalism itself, such as the buff you get from Dreaming Glory. That really is fantastic!
