My wife has reported some network lag whenever she goes out into the world. She server transfered from Sea of Sorrows to Northern Shiverpeaks and saw a slight improvement, but still getting similar lag. It ranges from 1-3 second lag into sitting there for a few minutes waiting for her client to catch up.
I have similar lag on my account as well, but it hasn’t gotten as far as taking several minutes for my client to respond – same servers.
