the engineering profession has been updated on the beta and it may take longer to level to the appropriate level to learn the de-weaponized mechanical companion and personal world destroyer. not too challenging, but not quite as simple/easy as it was when i wrote a previous post detailing these two pets.
both trainer learned recipes still require 475 engineering skill, but they have had their mats altered and now require more than just a few bars and bolts. one thing that many will be glad to hear is that the two companions are still bind on use. so start buddying up with your favorite engineer now! or start planning your way to 475 engineering skill if you happen to have the profession on your collector. ;P
