From what I have gathered this is only with Duty Finder. I can play on the server fine from what I gathered but as soon as I get in a dungeon I just lag to all hell, no one walks they just teleport and I'm dead before AoE even goes off. Need I add in the massive amount of delay with cutscenes?
AFAIK it's not my ISP, as I've already contacted them.. Twice. It started at like 4am Australian time and it's still going on as it's 1pm.
Such a grand birthday present, thanks SE. :) - The one day I can actually sit back and play without distraction is the day it decides to mass-lag.
