I'm trying to get my engineering to 375 can someone verify that the Khorium Scope schematics or Felsteel Boomstick schematics actually drop. I've been farming the Khorium Scope one for a couple hours and no drop i know its low drop which i'm willing to keep farming but i want to at least make sure they drop and i'm not wasting my time.

I just leveled Engineering to 350 and found out i can't even make the Gnomish Battle Goggles is there a release date for these as i dont think they'll be that great by the time they are actually released....
