Not necessarily. For starters, a technology class would utilize the mechanical type. I don't think any class in the game uses mechanical types. An example of a mechanical would be the ability to turn yourself into a Mechanical entity for X seconds. That comes from the Tinker hero class btw. Mechanical include immunities to certain status effects, the ability heal through repairing, and the inability to heal through healing magic. Viola! A completely new class mechanic.
Also it would be a class that can do physical range, yet be completely different from Hunters.
The rest really depends on how they're implemented, however, their potential for adding something new to the game is quite high. Look at Monks with melee healing. By their very nature, Monks added something new to the game. A technology class would be no different.
