"Goblins are known for their
mechanical expertise and clever, though sometimes peculiar,
inventions, and the
Tinker is certainly no exception. With his Claw-Pack/Hammer-Tank combo, the Tinker's ingenuity is undeniable. Though his parts may sometimes
fail and the occasional explosion does occur, the spirit and enthusiasm of this Hero are never diminished. There truly is more to the Goblin Tinker than meets the eye!".
"Engineers take advantage of their inventiveness to create an immense (and occasionally random) variety of helpful items. By
tinkering ceaselessly, and tolerating
malfunctions and misfires, an engineer can make utterly unique objects: sight-enhancing goggles, potent guns, robot pets,
mechanical mounts, and even more unusual trinkets. Successful engineers use their
inventions to solve problems and make life easier, faster, and better for themselves and their companions."
It's not comparing a Barbarian to a mechanical genius. It's comparing an Engineer to a Tinker.
