Why does the Artisan "level up"? Looking at the latest movie from Blizzard Jay speaks of the Artisan sort of level up as you help him complete quests. But the Artisan seem like such a MUST HAVE guy that I don't understand why he should need to be "upgraded", everyone's going to do it, it's mandatory. And since he seem to be such an important friend to have in the game the quests he hand out must be very simple not to loose the very poor players and we all know that Blizzard aim for the largest target group possible. So, what's the deal?
