New player here. I am thinking I would like to main Bard, Monk, Ninja if that is possible? I am just curious if that is something that would be recommended? Or should I level a tank type and healer type?

If so, what is the best leveling strategy. Should I work all of them up at the same time switching between jobs etc or should I get one to 50 or so before focusing on the others.

My thought is to level:

Pugilist 15
Lancer 15
Archer 15
Rogue 15

And then take Pugilist, Archer, and Rogue to 30. But I am just not sure that is the best strategy.

Thanks in advance.
