It isnt that the blue set is a scam/trap. Its the cheap and easy set of gear. Not quite as good, but certainly enough to get the job done. A set of un-melded Facet gear is worse(and potentially expensive if you buy it when its brand new rather then make your own). And sure the melded set of facet is the best we have at this tier, but melding itself can be an expensive proposition if you go full bore. You hopefully make an informed decision about what is right for you, and modify your tactics to account for it as needed.
