Nobody has attacked the tinker concept. they have only attacked you're incredibly stupid and restrictive version of Tinker. You have never once given a legitimate point for restricting Tinker to goblin and gnomes. Literally not a single point. So you constantly move goalposts and talk in irrational circles instead of admitting you're wrong for once. As a result, we are 163 pages in because you refuse to admit you're wrong and phrase things in a way you know will spark arguments.
