You appear to forget that NO ONE will be able to fully BiS ALL jobs while that gear is still relevant. The 'farm more' you speak of is going to be the 'no-lockout on Second Coil' spamming after 2.4 is released. You know, when people are specifically picking which class they want to improve with Third Coil gears, and foregoing the rest. Exactly as Zephyr stated, correctly.
Edit:
Back to being on topic, I think the de-synth caps are a good thing and do not detract at all from the spirit of the armory system. As far as I understand it, a person can STILL craft everything. You will need to acquire the 'unique' de-synth drops from someone else though. Not a huge deal. If everyone could de-synth every item, we'd go into dungeons where everyone would greed roll every item, because they could de-synth it.
INB4: But that already happens.
Not as often as doomsayers want us to think. People generally greed for off-spec, seals, and glamour.
My understanding is that CT, Primal,and First Coil gears will all be de-synthable. These aren't redeemable for seals, so you'd compete with people who legitimately have use for the item for it's stats, appearance (people who may loot the item once and be done with it) and people who can de-synth it if it's one of their specialties (people who may Greed lot on that item 100% of the time that it drops). Mastering all de-synths may increase the game experience for the people who have all DoH mastered (including myself) but it would be at the cost of the game experience of people who do not have them all mastered, and are actually seeking items for stats or glamour (also myself).
