Cool post. I agree for the most part, however, herblore only starts making money once you can make prayer potions. Besides you need money to pay for the supplies. I'd also recommend going to waterbirth island and picking up snape grass and depositing it with peer the seer( you either needed to start, not finish, fremennik trials or have the easy task done). Snape grass is 450gp each so you can easily make 200k+.
