This game needs depth, Please implement a second weapon (playstyle) for each job

subjob snip

Nooooooo nonononono.

Currently, leveling a secondary or tertiary class is entirely optional. The moment you force people to take Subjobs and then level them you remove that as an option. You then have the minmaxers that come along and numbercrunch to find the "perfect" subjob combination and its no longer variety.
You HAVE to be a Monk x Dragoon in order to obtain X Stat increase and Y skills in order to complete Z Raid.

Cross Class skills right now are VERY useful, but none of them are truly mandatory, and no content requires you to have them. Subjobs like the ones in your examples would be not only mandatory but force the Devs to tune content to the expectation that everyone including the leading edge of Raiders will have them.

It was said in the E3 live letter, which there is no Q&A sadly, but i found this :

Not really about jobs but :

Please note the word CLASSES. He is referring to additional, new classes (like the Rogue is a new class) NOT additional Jobs. Every Job only has 1 base class. Therefore, he is referring to new Classes of Tanks and Healers, i speculate things like Samurai, Dark Knights and Geomancers etc.
