Zil said:To use your mechanic analogy, let's say the mechanic hoodwinked you into getting a bunch of repairs you didn't really need. Sure, he has a right to make money, but perhaps not that way.
I think you are correct, in that people think that way.
I don't find it to be a valid comparison, for two reasons - one is simply the importance of the issue at hand. If one does not have a working vehicle, one's entire lifestyle may be in danger, requiring a multiple-thousand-dollar expenditure to correct. Basically, the mechanic can play off a customer's fear. I don't think that really applies to D&D.
The other is more important - in order to hoodwink you, the mechanic has to lie. WotC doesn't have to lie, here.
