I know. But you severely misunderstand what reason I posted that for. It was not to "suggest" the classes being rolled into one. I wouldn't want that either. It was to emphasize the point that considering the Mastery/Folklore books as "end-game" is suggesting that the classes shouldn't be made more unique in how they play, or at least what they have access to. Something I disagree with.
One way they could be made different is make some sort of instance. Restoration of Holy See is a good opportunity, especially when they stop support for 32-bit Windows. They could give the players an actual ability to influence the look through the choice of what to make.
The knights make a new squad to patrol the town and want the Warrior of Light to help with arming it properly. The Warrior of Light turns in armors and weapons of their choice and can see those patrols with those items equipped henceforth.
Similarly, the poor people from the slums could get new clothes from Weaver in the same manner. There could be some facility built that would use furniture made and chosen by Carpenter.
A restaurant that would serve the dishes made by the Culinarian.
Make it impossible to turn in anything but your own stuff, maybe by making it require Collectibles, and you start making a difference in-game between them. You can only change the world in what respect you can actually commit to.
Of course, this is just a suggestion, and only a rather small thing in the grander scope of things. But right now you don't need any of the crafting classes to do anything at all, really. Except in-dungeon repairs. You can just throw your money at other players. And at-level, that is actually quite often cheaper too if you need a high quality item for job quest or some such.
Basically, I don't want them to be turned into a single class, either practically or metaphorically. That's why I hope for something that will make them genuinely discernible from each other in the game itself.
