Job System Timeframe

[Koronos]

Well the biggest question is going to be the PLD/GLA one, which is going to be better for tanking the open ended GLA with Emulate, Accomplice, Defender II, Cure III, and Sacrifice III attached to it or GLA which is potentially going to be restricted and not have some of said abilities.

While not the biggest question by far, imo, you do bring up a good point. The jobs must be significantly more useful in a party setting than its corresponding class, otherwise why even implement a new system? This will be true for all jobs, in almost all circumstances where a party of 4+ is required. If this isn't the case, SE will have failed. I do not, however, think that grouping with a normal class will be restricted, beyond however they decide to balance equipping cross-class abilities. Classes will remain useful in solo/small group settings, and I'm sure other circumstantial situations, but endgame (and hopefully effecient sp) will be jobs > classes.
