Because the blizzard has greatly weakened the efficiency of the project, the low-level projects are basically useless, and at the same time, it has caused the assimilation of the engineering branches. In other words, there is basically no actual difference between the two branches now, and the unique drawings that can be learned are basically of no practical value, even WLK. The end result of the Goblin project is that a big bomb will do harm to all the enemies around you and yourself. It is obviously not cost-effective to use 80 thieves, because there are AOE skills of flying blades, and other occupations have no use value. The last thing in the Goblin (Dwarf) project is the eyes that can see through armor, and players only wear underwear (not when orcs are all over the street).

Moreover, all kinds of motorcycles and planes do not require engineering majors, and someone will help you at a little labor cost.

The only thing to pay attention to is engineering professional enchantments, such as shoes+lethality +4 seconds running speed and glove acceleration. But products, jewels and inscriptions also have very useful enchantments or gems for professional use.

As for the launcher, there is only one kind of WLK, both of which can be learned, that is, it can be launched anywhere in the Arctic at will, so Area 52 and Wang Yong Town/Garkison and Feng Daoshan are important issues to be considered.
