Since the Skills page has been rehauled, I suspect the page was only assembled with the Engineer class and its two master classes because the names were in the data files or sumthing along the lines ; they were not implemented in the game yet, per se.
The real question is : When, or can we expect them anytime soon?
So long as there's no "We've decided to scrap the Engineer Class" announcement, I don't care what rumours come around. I just want to see it come about! Though, ideally, I'd like it if Nameks and Majins could be Engineers too.
No as it stands is a specific human class there's no indication that Namekians or Majins would be able to get it. Course it could be said that there's no indication to the contrary but since its something based around Bulma/Capsule Corp etc and the classes are all atleast for the biggest part loyal to the series i'd doubt that its more then just humans.
I'd think it more likely that there'd be 2 more classes not yet revealed IF majin and namekian would get a 3rd class when engineer would be implemented.
I don't really think that humans having a 3rd class while the other 2 races don't poses a balance issue though. And since the game is already quite lenient on the requirement of healer/tank i'm having some doubts about the potential roles of the engineer.
Don't see it becoming a healer type, tank would be possible with mechs i guess.
Q. 인간 종족 스킬 마스터를 보면 엔지니어라는 직업이 준비 중이라는 것을 예상 할 수 있다. 언제쯤 업데이트 될 예정인가?
준비는 시작하고 있지만 조금은 긴 시간이 필요할 것이다. 엔진이어는 인간 종족으로 등장할 예정이며 원작에서 캐릭터들의 근접 전투가 중심이 되는 것과는 다르게 총과 같은 원거리 무기와 기계 장치 등을 사용하는 새로운 패턴으로 유저들이 색다른 느낌을 받을 수 있도록 제작 중이다.

Q. According to the human race engineer master skills is preparing a job that can be expected. When the update is supposed to be?
Ready to start, but it will require a long time. Following the engine is expected to emerge as the human race from the original character of the melee combat unlike the central arms and machine guns, and the same distance to use the new pattern, so that users can get a different impression is made.
