Servers deteriorating recently ?.

I've played this for a few months, and i play other online games daily, so when i says i RARELY experience lag or latency issues , i mean rarely.
But recently in D2R - after ROTW release - i've experienced frequvent lag in D2R, to the point where i can be surrounded by enemies
and hitting them but nothing happens, then suddenly i get teleported back to the other side of a doorway.... horrible lag.

So i'm asking, is anyone else experiencing this lag since rotw release or ?. I'm located in scandinavia with an optical 100mbit internet
and no damn router so there's no problems ON MY END . There's has to be something that's degraded with D2R's servers since rotw release.

I noticed this myself. In Korea, playing on the Asia server (which I think is physically located in Korea?). Just now my baby Amazon was getting beat up by creatures that, on my screen, were in another room.

I never noticed this before. It's dead early morning here, too, so I can't imagine it's overload. What's going on?
