I got very high ping with Blade & Soul Vietnam server. They might changed data center and IP, so the node currently connect with wrong destination server. Please check it.
You can try FastConnect mode.
Then, as workaround you should use one of methods at Unsupported Games. And if you want to see it officially at Mudfish, please send me some game packets using Packet Capture with Mudfish link while playing the game with Full VPN mode.
I need some game packets to register new game.
