It's Nutaku, and it feels like I've got fucking dial-up. Also worth noting that the game isn't taking up bandwidth while doing the 5 second pause when you use a skill or press Attack like it normally does (I use NetLimiter and it shows next to zero usage). It's acting similarly to how it does when you first use a skill, burst, or eidolon.. only that it's doing it all the time on every part of the game.
