You can't get it once you hit level 31 or higher. I think the point was to have a trade-off for being a high level player. That was my original theory, now I think it was done because of this:
You get all your crafting while you're grinding, once you hit level 31 you don't have to worry about chadztext. Not everyone wants to keep getting chadztext if you are wearing equipment that isn't on your crafting list.
But like it's been said, this is going away soon, so I wouldn't worry about it. I'd guess by September we have a new crafting system, and a new version of strategus.
You heard it hear first folks.
