A little lube...

Engineers rejoice. We are actually getting somewhat of a buff for once. Nothing to big(at least not until actual numbers are released) but something is always better than nothing.
Our personal enchants are now the same or better than what others can give us and it still retains the fun engineering ability.
now if only they could make wrist enchants that allowed us to fly for a few seconds... or even just shoot straight up... :-D

update list with less details about some things and more about others... just read both. :-P

• Added a new Mind Amplification Dish attachment for helmets, allowing engineers to control other humanoid targets. Some restrictions apply: does not work in Arenas, dish sometimes reverses targets, unable to stack with other stat-improving head enchantments and makes your helmet look... stylish?
  
• Added a schematic for a Goblin Welding Beam that can heal friendly mechanical or vehicle units.
  
• Alarm-o-Bot functionality changed. Materials required reduced.
  
• Box of Bombs no longer requires an anvil.
  
• The Cobalt Frag Bomb now incapacitates enemies within a 3-yard radius. A short cast time was added, but they are usable while moving. This change applies to any Cobalt Frag Bombs already created. The existing recipe now makes 3 at a time.
  
• Engineers can now learn to create a portable Wormhole Generator for Northrend. The Wormhole allows them to travel to different locations in Northrend, although the locations are sometimes in dangerous places.
  
• Increased benefits from Hyperspeed Accelerators, Hand-Mounted Pyro Rocket and Reticulated Armor Webbing glove modifications.
  
• Increased the passive bonuses provided by Springy Arachnoweave, Flexweave Underlay and Nitro Boosts.
  
• Increased siege damage caused by Saronite Bombs and the Global Thermal Sapper Charge.
  
• Mote Extractor now has innate tracking for gas clouds while it is in your inventory. Tracking of gas clouds has been removed from goggles.
  
• A new repair bot has been added, and his name is Jeeves. He is the ultimate gentleman robot butler, able to perform all the mundane tasks of repairing, selling and buying junk for your entire raid. Additionally, he can open bank boxes for skilled engineers (350+). Jeeves is not destroyed when used, but due to pressing engagements, can only be summoned once an hour. The schematic for this handsome robot was said to be hidden within the parts of another robot – hoping to be found by an engineer one day.
  
• Nitro Boosts: Now have a 5-second duration.
  
• Potion Injectors now increase the amount gained by 25% when used by engineers. Quantity produced by recipes for Runic Healing and Mana Injectors has been increased.

• The Spynocular belt attachment has been changed to a Frag Belt. The Frag Belt periodically produces a Cobalt Frag Bomb that can be used from the belt every 10 minutes (never runs out!).
