Me too, is plagued with this as a PS3 user. I submitted a bug post in early september http://forum.square-enix.com/ffxiv/t...ngeon-instance and I was hoping it would be fixed sooner. I guess it doesnt get enough attention, so lets fire this thread !
Is clearly an instance server load issue, Im mostly encounter this on sundays, where lag spikes are more frequent. It has to be fixed.
