ninja/rogue going to be over-played

[Felis]

I wonder the achievements and titles for have all 50 on jobs will be reset.

Never happened at ARR launch with Arcanist as new class

As I posted in the other ninja + scout theard in general discussion.

Ninja will be available to everyone or only to those who cleared the main story?

To everyone who have Rogue at level 30 or higher and another class at level 15 for the first ninja job class.
Another question is if Rogue is a starter class or if it need to get unlocked.
