Server optimization, and general expectations.
It is no big secret that since early access, Square Enix has shown how ill-prepared they are to manage a game as big as Final Fantasy. This evidence comes in the form of full servers, disconnection errors, and poor game performance. Despite upgrading their server hardware, I still experience R(0) lag spikes, and due to the culling of textures large fates, such as Svaras flight, are impossible to participate in due to Svara herself being culled/disappearing. To add icing on the cake, me and some friends just tried to participate in the odin battle and were among the first to get into the once in 3 day event. Unfortunately, as more and more players piled into the small area that the Odin battle took place in, we were all disconnected from the server due to the servers not being able to handle so many players in one area. Consequently, my friends and I all started receiving Error 90000 and could not log back into the server.
