I was reading Keith Baker's Site, and he mentioned a class that had been considered for Eberron, the Journeyman.
One of the reasons I do enjoy Sorcerers so much is that they can play the reluctant adventurer, power is their birthright, but it's not like the other spellcasters that have pursued their power, made it their profession.
And while DnD has always made PCs the heroes, it might be fun to play the Xander, or heck, a Doctor's Companion. I could imagine a DnD campaign with an Artificer and their magical box and a bunch of Journeymen that got caught up in the ride.
Journeyman sounds interesting! I was just going to say, in Old School Revival circles there were some classes based on Alice or Dorothy, an unexpected hero who perserveres through mostly charm and much good luck - the Journeyman sounds like a matured take on that and could even combine elements.
