Having the same issue, hiccup-style lag, very noticeable in dungeons but also happens in the world as well. Seems to vary depending on time of day (it's worst during prime hours) but always present to some extent. Quite certain it's not my connection, I've been monitoring it and I have not seen anything unusual.

Here's the IP my game connects to:
