I find it very hard to believe that they deliberately lied. That they deliberately created a unique job design that was mediocre and tried to sell it as amazing when they could actually make it amazing for the same amount of work and a whole lot more player satisfaction.

Maybe they're out of step with their playerbase and really do think it's a good design. Maybe it's a "cultural difference" and all their playtesters agreed it was a good design.

Whatever it is, something has gone wrong between how they described it and what we actually got, but I will assume lack of awareness over actual malice.
