depends how many bots you run if it's one its harder ofcourse i have a set up 5 accounts herbing 1 milling etc etc makes me 80k a day and i run this x2
Your question is still pretty tough to answer, since you're looking for the safest. If you only have one bot there still are different ways to make money. You could gather herbs and have inscription for your second skill and mill down the herbs and make the enchants to vendor or you could just gather herbs and mine and sell raw mats on ah. But as you know, gathering is not so safe right now.
