It will be based on the vendor sets, just like battle content is based around the sets they can obtain from the vendor/drops. They would not screw over every single person who opts for the vendor sets - that's bad game design, I am extremely confident in saying without a doubt that a scenario like that will not happen. They cost significantly more than the 170 versions and are not designed as intermediate gear.

Those stats would likely be bare minimum though, agreed. But it's far more powerful to know a ballpark, so that you don't need to shoot for something crazy like 919 craftsmanship and 860 control just to be able to initiate the craft.
