I've just been saddled with the single most useless dwarf on the planet. I ran him through DGC and he got these results:
'Guidance for: Athel, ♂
He has the look of a good Socializer. He will make a poor Miner, Bowyer, Carpenter, Wood cutter, Engraver, Mason, Animal dissector, Bone doctor, Crutch walker, Surgeon, Suturer, Butcher, Dyer, Grower, Milker, Miller, Tanner, Thresher, Fish cleaner, Fish dissector, Armorsmith, Furnace operator, Metal crafter, Metalsmith, Weaponsmith, Gem cutter, Gem setter, Bone carver, Clothier, Glassmaker, Leatherworker, Stone crafter, Weaver, Wood crafter, Strand extractor, Pump operator, Siege operator, Swimmer, Armor user, Biter, Dodger, Wrestler, Comedian, Observer, Close combat dwarf, and Ranged combat dwarf. He seems like a very poor Trapper, Diagnostician, Brewer, Cheese maker, Cook, Herbalist, Fisherdwarf, Mechanic, Siege engineer, Appraiser, Building designer, and Organizer. He would be horrible as a Record keeper, and Student. He is too direct to Lie.'
Letting him die would be a mercy, and it will probably happen, because I'm embarking on a tundra.
Four of my dwarves are clumsy, some very much so. A couple are flimsy. Three have meager creativity.
I'm not sure this is a dangerous settlement so much as a dwarven eugenics program.
