This has plagued me somewhat for a while but never so badly as after 2.16. I'm having spikes of lag where I can't do anything at all for 5+ min and often get 90k disconnected altogether. Tonight this happened during Ifrit HM and then when I returned from the duty instance, everyone was shouting in Limsa about crashes and disconnects. What's going on SE? Is this something you're planning to address sometime soon?
Thanks
