It’s almost impossible to describe gnomes as a whole in Warcraft without using Engineering terms.
Engineer, Tinker, Inventor, are all great things that I love being, but if you play an gnome, and you don’t take engineering, suddenly the rest of your race is entirely irrelevant to you. That doesn’t happen to Forsaken or Goblins that don’t take Alchemy. Gnomes are solely defined by one profession in the game.
So here is the challenge. Describe Gnomish Culture, without using words like Engineering, Tinker, or Steam-punk.
