I receive disconnects every to every other mission only in instance storys and it's exclusively during either the talking cinematics or occasionally after choosing an option talking with a npc. These disconnects almost ALWAYS are at the end of the mission. My internet is extremely good, with also being wired, my hardware is also not the issue. These disconnects are most certainly a bug from the game. I just got into GW2 a week or two ago and found it so enjoyable that I got both the expansions to get the full experience. Unfortunately these disconnects are making the amazing story mode borderline unplayable. I pray they fix this.
