Okay, if you look at the picture representing "The Resistance" in the job selection screen, you will only see the shadows of two characters:
However, elsewhere in the quest data they also added jobIDs for the Mechanic class (3500). And yet the Resistance only has two types of characters.
DOES NOT COMPUTE.
So what's going to become of the Mechanic class? It was assumed that there would be three resistance classes. Is it that the Mechanic class is not done and will be added later, or is it that the Mechanic will become another "Limited time only!" class? Perhaps the creation of the Dual Blade and its success has taught Nexon that limited time classes are better for their bottom line.
