Tinker controls 7 pieces of gear, has the best-selling top-tier outputs of any craft, can make hope tokens, and can also make food. I have 3 of them, and I always suggest every new player start with a Tinker as their first character, regardless of class. I don't think there is any point to being anything *but* a Tinker if your characters are going to be either self-sufficient, or if you're only going to play one. If nothing else, selling the fruits of prospecting alone will make you enough money to buy anything you'll need in-game.
