but while i was leveling inscription the other day, i found a bug which allowes you to use only 1 herb every time u mill instead of 5.
what you do is:
1. get 5 herbs.
2. start milling.
3. before you are done milling, remove 4 of 5 herbs to a new slot in bag.
and u only used the one you dident move, and still have 4 herbs left.
seend that you can get few 100-1000 gold from ink, this exploit was slow, but ok to earn gold.
now you just need those buggy places were tons of herbs spawn,
like alterac mountains, near the 2 houses down by the lake.
Here is a video for those who can't get it right by reading my **** english
Tho, the quality got raped by youtube
