Yeah, I guess Mind continues to be the dominant stat ... for now.
As for the skills/job, thoughts on my part were; mechanics are all about understanding mechanical principles, whereas repair ponies might need to have knowledge of how to fudge together parts that were not designed for their use so both might apply.
But hey, if you want to argue against it, more than happy XD.
Oh and Amish, I agree with the special purpose applying, but you rolled high enough that it's rather moot. :)
