Crafting does require harvested resources though, and selling real items is going to be more profitable if you are a good business person than doing work orders (as killing regular mobs is not as profitable as fighting boss mobs).
Dedicated harvesters should be able to make a good living if they haul in tons of quality resources. The dedicated harvester will have the most success as an adventurer, since harvesting is dangerous and there are lots of things out there that want to kill you. Dedicated crafters can dabble in harvesting as well (but it's not required). Getting the more valuable resources will probably require some of your friends to play bodyguard though.
If dedicated harvesters are good at business as well, they could develop a very profitable relationship with a crafter or number of crafters. Ė 3 December 2005
