Player XP gained from gathering herbs and mining needs adjustments - it's way too low at the moment and doesn't even seem to work for herb gathering beyond herbalism skill level 51. I think the herbalism issue is related to the fact that even quite high-level herbs stop giving skill-ups long before they should, and this in turn is likely related to item/object level settings in database + possibly wrong formulas for calculation of skill point gains and player XP.

This is the best resource/description I could find on the topic of player XP from herb gathering and mining so far, but more research will likely be needed in order to get the system working in a Blizzlike fashion (most notably it'll be necessary to find and implement correct levels for each herb and ore node and items they can yield):
