The disconnects had been happening to me recently and I did get suggestions from Support to make sure my firewall and antivirus was set to exclude GW2 and two other files. Everything was going great, I did a few more PoF story instances with no problem, then I was kicked at the very end of To Kill a God. It stinks to have completed the instance, feeling pretty good at the accomplishment and then losing it all because of some silly glitch. I'm not really up for running it again if the same thing happens. RNGesus is now affecting instances as well, I guess. I did update my support ticket and hopefully there's some "magic fix".
