The Engineers was necessary in WoW, people want to design or blacksmithing in WoW, Engineer was so important for this object. We know you are interesting group of crafters, having the ability to craft a wide range of items (though often landing them with the better items in their inventory i.e. those that only they are able to use). Other than gun scopes, they have not really been able to do much more with their abilities than create mote extractors and goggles.
Engineers will now be able to craft and implement enchants on their own items to create advanced items only available to themselves – such as parachute cloaks, for example. However, Engineers will not be able to stack regular enchants with the Engineering enchants.
With the arrival of Wrath of the Lich King, however, they have been given hope, with the introduction of a few choice new recipes that will (though probably not massively) change this, and will offer numerous fun new options and bonuses for leveling up Engineering all the way to 450.Nitro Boosts – Will allow Engineers to add nitro boosts to their shoes for a major speed increase that will last for 5 seconds.
It is more than likely that one of the most popular new sets of schematics is going to be the addition of mechanical mounts, in the form of a hog and a chopper (motorcycle-like machines that will only be available to Engineers). Additionally, new craftable pets have been introduced, bringing with them more depth to the value of these items which have always gained the most gold for engineers.
