Recently I realized that whenever i am in a dungeon ak or Titian or garuda hm I always get a 2-3 second lag. During this lag everyone will freeze except for me, i can move around smoothly attacking and casting ( skills are not lagging) but the damage effect doesn't show until the 2-3 s lag is over. This is getting extremely frustrating, trying to predict what titian will do in the next 2-3 seconds doesn't help. I tested on gw2 and there is no lag in dungeons at all and through out the entire game.

I am at NY and I have 20 ms from the NA data center and using TWC ( my fps doesn't drop below 48 even at lag) I move around smoothly just people and boss freezes in time. ( time stops for those 2-3s) I dc few times today outside of dungeon and even got error 9000 twice. I asked people in my party no one is having this issue. It is like a spike lag? When the 2-3 s lag is over I am back to normal but then I will lag again. I doubt it is my internet because my last few wins I didn't lag at all http://www.speedtest.net/my-result/3028200770
