I mean I don't know their situation and they may be rushed or something, but it's been pretty clear with all the problems aside job balance that the patch wasn't thoroughly tested in some areas. In ARR Ninja was balanced around their number crunching and players found out a better rotation, making them ridiculously stronger than the developers intended. A test server was brought up several times by the JP community too, I think it's overdue. I've been watching this game get stripped of anything remotely interesting in terms of job balance since feedback from the First coil of Bahamut. There's a lot to like about the game, but encounters aren't one of them aside aesthetics.
