I completely missed that line, thanks Malothar for pointing that out.
Uhm... I share your concerns.
First I don't get why they call it "add of a system". Bad translation? Despite the wording it seems to me they're just talking about new JP categories involving job traits.
Anyway, assuming they obviously meant just the default Job Traits and not the merit ones, I think every job gets at least some possible nice option. Some more, some less, but all jobs get at least something interesting.
It kinda depends on what SE will choose though (like Resist Virus for WAR and Resist Blind for SAM

).
Only two jobs that would get kinda fucked by this system are BRD (all options are really meh) and BLU (they have no basic Job Trait).
They'll probably think about something unique for BLU, and they will just ignore BRDs who will have to manup and deal with it
Speaking of job traits, I wish they could change the way they're listed in the JT menu and add the tier number next to the JT name (and maybe release a detailed and updated jap-only datasheet with all the exact % numbers for the JTs...)
@Byrth
They've done that in the past as well I think.
It was probably something they had originally scheduled for November but then pushed it for December.
For us it makes no difference because it's the first time we see that timetable, but they probably planned to release it sooner and because of that kept track of all the internal changes (like this one) which make no difference at all for people who see the table for the first time, like us.
