can I master every job?

[Betelgeuzah]

so if i want to play as a strength type i can put points into strength and vitality and then when i play as acaster type i can put points inot int and vit and they will all be independant of each other?

Yes, as long as its not SCH and SMN as their points are shared (if you put INT into SMN, your SCH will have the same INT). Any other job has individual point allocation.

In the future similar setups as with Arcanist may become available for other classes (more than one job per class).
