I can say older content is rather dead, but it isn't because of ishgard its because its old.
Even when Ramuh Ex and Shiva came about ....finding a party for the older primals were non existent due to the loot they dropped
Pony farming is over as either by now you have them or you don't.
Most players are to caught up in trying to catch up with newer stuff to even indulge in the older primals
Other players are trying to down the new primals that actually give them an edge before Alexander.
ARR maps are dead, HW isn't dead
