Petdo, you do make an excellent suggestion for many players starting out, but other DoH jobs do make money, albeit with more time invested.

Still, your suggestion that players learn how to create their own shards is a good one, and personally i've saved untold amounts by breaking down fish and crystals. The only drawback is that this process is actually about triple the time- sucker compared to other DoH, since you're not gaining anything once past XP levels for these synths, and solely to support other crafts.
