This isnt true. Ive heard rumors about Balmung being low on apartments, so thinking maybe this was a Crystal specific problem i traveled over. Picked a random ward in Lavender Beds(19 if that matters), and less then half the apartments were taken. If the first ward i randomly picked in a popular district was less then half full, i see no need to randomly pick others to check. There just ARE apartments still, and apartments work just fine for chocobo dying.
This isnt me saying the system shouldnt be improved, this isnt me saying apartments are just as good. This is just me saying that the statement above is false, that server isnt out of apartments.
