So, this Scrip system...

[Nashred]

A8: The specialist system is a new system for Disciples of the Hand, and you’ll be able to undertake a quest to become a specialist from level 55. It’ll be possible to become a specialist in three classes of your choice. By using “scrips” you’ll be able to change which classes you specialize in afterwards. By setting a specialist class, you’ll be able to learn special actions. Currently, in order to make some of the higher difficulty recipes, there is a necessity to level various classes for their actions, and we feel that the difficulty has spiked a bit. We plan to improve this through the specialist system, so you can think of this system as something that will allow you to broaden your options by either playing as the classes you really like or enabling you to use all of the classes.

So it looks like you can specialize in 3 jobs. Also does it man you can only take 3 jobs past 55?
How does this make it easier for the casual?
Honestly the token artisan gear made crafting pretty accessible for all..
