I'm taking advantage of the free play-time the current event offers - or at least im trying to. However its really hard to kill mobs while looking at the same frozen screen for 30 secs then selecting the next mob hitting attack and looking at the next frozen screen.
Is there going to be any change to the duration of the event because of the current Lag problems the European servers have?
I think it may very well be a router or a switch somewhere on the pipeline between you and the server. Likely very close to the server, if nothing else is significantly affected.
