The asuran things maybeeeeeeeeeeeeeeee.... but i'd say theyre somewhat different because thats not something tied to the game or anything its. just like oh hey you preoredered ff13.. kinda likehow some minions are connected to buying the soundtrackor something years ago... and i personally consider stuff like that to be different to actual earnt game rewards and such.. so releasing the asuran guards again yeah totally fine with that cos its just a preorder thing not actually a gameplay thing... but stuff like the white ravens or even the legacy chocobo actually represent something in the game. so thats where they need to be more carefuli think. but again even if they just made the whiteravens they dished out freely a replica version that would have made all the difference and prevented a lot of the uproar. and there would likely be insane levels of backlash if they ever handed out legacy chocobos for the same reason. because they represent something in the actual game.
Honestly thats something thats quite tricky to make a totally fair assessment on.
Part of the reason why it became difficult to farm old Ex primals was down the fact that players know they can literally just unsync it and run it 10 times easier and 10 times faster next expansion and given that the other incentive (weapons) on old ex primals were already obselete and outdated thus unwanted, theres no reason not to wait till the expansion and just rofl stomp it.
Another reason reason why parties for old ex primals don't fill today is because so many people have already unsynced and steam rolled there way through them.
if you took a thousand players you might find 900 of them have mountx.. but if unsynced was never implemented that number might only be 300. whcih then means if you put up a party finder for mountx today. 700 people would potentially need the mount and be interested in joining instead of just 100. which would then potentially mean that even today parties for mountx would still fill up.
