I really like their slow leveling design. It gives alot of weight to your abilitys that you achive with every level and even if its just a "poor" masterwork item you wil find in the early game, it will serve its role as power up and stand for its name. Actually a strong item instead of beeing something you casualy skip in other games. Beeing level capped in game with a slowed down progression helps you alot to find more intresting playstyles. Where you have to be forced to find ways arround certain enemys or big hordes of goblins. Rather then just blasting the heavy wooden door that leads into the castle with your fireball and then blast the group of goblins with your fireball and then blast the magical treasue chest with the fireball.
