I have characters on Ragnarok, Gugnir, and Sargitanus. There are imperials in pockets... like around Clearwater (Sargitanus) where there are hundreds of imperial troops mostly level 50... and they attack you if you try to get through them. Around aetherytes that are infected there are mobs of Deepvoid high level critters. Still, pops are sporadic. On Ragnarok it seemed quieter... noises like thunder or ship motors but not much to be seen. On Balmung I wandered around mostly in the cities and nothing was happening. Strange the servers should be so different.
