It is, without a doubt, an ANET issue. Our group has players from all over the US and Canada. Different ISPs, Different distances to ANET. Totally different traceroutes. But, we are getting a large number of our members booted ( DC'd ) at the same time. Pretty much always during the end of story cinematics. ANET is fully aware. ANET is doing sweet "F" all to fix it. It has been an ongoing issue for more way than a year. ( And is fast becoming far worse ). Always the same BS from Tech Support. They blame you, your ISP or your grandmothers apple pie but, they will not take responsibility. About all you can do, when the final cinematics are running, keep moving, hitting skills, whatever, but, keep files flowing between you and ANET and, hope for the best. It "may" help if their server doesn't see nothing coming in and presume you are gone which, as I understand it, triggers a disconnect. Whatever, don't count on ANET to do anything. Many have tried, many have failed, many have quit GW2 and moved on to other games from other developers. If you put in a ticket, they will ask you to send a file that doesn't exist because you got booted. They will ask for a traceroute diagnostic which, you will send and then you will hear nothing. I know we have at least 20 to 25 in our guild who are looking for another game instead of this one. Good Luck folks.
