People keep spouting this nonsense. I know you're just regurgitating things Yoshi said (and he says alot of crap), but I'd beg you to please assess the statements for yourself, because what you're basically saying is that they have taken the Armory System - which was the flagship feature of FFXIV - and then said "oh, yay, you can now use the armory system to solo" even though you always could. That's such a demotion of the Armory System if it's now merely employed for soloing. And anyway, you can probably solo with Jobs too since soloing is such a cakewalk.

Besides, the definition of an armory-system-user as a solo-er and a job-user as a party-animal, is such a huge upheaval of the original philosophy of the armory system. That in itself is enough evidence that the armory system has been replaced (or should I use another word since you'll start throwing Webster's dictionary at me if i keep using this one?).
Well, to be fair, according to the player polls, people wanted massive changes from the original philosophy of the game. So I would not at all be surprised if the Armoury system largely goes by the wayside.
