How can they add more classes and make them unique and have their own flavor?

[Keiko_Kumiko]

I remember I read somewhere that Yoshi P said that they will add more jobs instead of giving jobs more specializations (IE DPS Paladin, Heal Paladin).

Dancer I can understand being different because I heard it is a melee healer(?)

How can they make the new jobs unique enough to make them not be copy and pastes/combination of the other jobs we have now?

I think that it's easy to create more different classes and jobs, but to make each of them more unique, SE/Yoshi really need to instate elemental and attack properties.

Fire monsters weak against water/ice, absorbs fire attacks, ice monsters weak against fire, absorbs ice attacks, hard scaled monsters impervious against slash attacks, flying monsters weak against shoot attacks, etc.

The first time when I played this game, I was surprised that elemental/attack properties was missing, because in my opinion THAT is really what makes every class/job, and frankly, the entire game unique. Without it, there is really no point in which class/job you choose, because every kind of attack will always result in the same outcome.
