There are no "other two beta servers". This has been stated many times in the past. Mornlands and Lamannia are not beta servers or test servers, they are preview servers. The don't often make changes based on the feedback from these servers unless they are show stopper bugs.
This isn't even a bug, it is part of them balancing the crafting system while in beta. As long as they don't reset all the crafting XP and levels once the beta is over, I don't think there is alot to complain about.
