Apparently, I also get the same issue. and I am from a similiar GMT, which is GMT +7 South East Asia. I play on Eredon's Terrace. The ping suddenly spikes a lot, and the game becomes unplayable. I have tried disabling my firewall, and the game still lags. I tried running ping test and playing other games and it seems fine. Things that I have tried: Disabling Firewall completely and allowing Guild Wars 2 CoherentUI_Host.exe on Firewall.Resetting my WiFi, and tested it on other video games, it runs fine with 25 Mbps and 7 pings per second.Repairing the launcher.Testing other accounts and being a guesting in other server.Using a popular fast VPN (Nord VPN) and choosing United States server.I have sent a ticket a while ago, and I really hope I can play Guild Wars 2 again without too much delay. I mean before this issue, my ping was around 250, and with tiny bit of delay. But now, doing skills takes 3-5 second.
