Similar issues are being had on Leviathan. My current statistics show that I am Sending around 20-30ms and receiving 5000-6000ms. Ran ping and speeds tests on my end and both returned well within their normal boundaries. As with Acquitor, the majority of the problems seem to come in the instanced content. My computer rig is also well above spec for the game, and I have party members and FC mates reporting their own troubles while trying to partake in dungeons.
