Herb Patch Gathering

I'm fairly sure the success rate is the same as the equivalent herb patches in dungeons. My elf with rank F herbalism fails two out of three tries to pick base herbs, while my human with rank 9 or 8 or so fails once every five tries at most. I haven't tried picking more difficult herbs with my elf yet, but I imagine it'll also follow the pattern.

Herbalism affects how fast you can actually gather the herbs. As a result, in places with a fixed gathering rate which isn't affected by herbalism, the picking will take quite a bit longer; for example, I can clear a base herb patch out in the field in the time it takes to gather two or three herbs from an herb pet, assuming all successes on both.
