To be fair... I don't really know if I ever saw an MMO free oe otherwise that would ever nail. The replayable content isn't exactly easy to nail. Just look at whatever they tried to implement in any of the WoW expansions. Island expeditions, Tower of Thorghast. Each on paper supposed to give player something to do yet the rewards were so lackluster and yet tied to current progression so players were forced to do them alongside dozen of daily activities which only lead to the burnout.
There's also the thing that unlike some other games out there FFXIV doesn't throw the old content to garbage every time a new expansion drops. And a large portion of this patch went into reworking old dungeons, implementing Duty Support and bringing old markers up to the current standards. And I'm grateful they did put their effort there.
