He's correct on the "VPN will solve the disconnects" thing.

As a Swedish player on Excalibur, after the DDoS shenanigans that were going on before the update, I've been more or less unable to play the game as well.
Constant disconnects as soon as I try to use any skills, mount up, teleport etc.
Were unable to play dungeons or do fates and so on.

I stupidly teleported to Quarrymill and instantly got the 90002 error, then after that every time I logged in I would get disconnected with the 90002 error since my character were still in Quarrymill.

Tried logging in with WTFast and now I'm able to play again with 0 disconnects.
It's ridiculous that I'm being forced into using a vpn service after being able to play this game up until now perfectly fine without one.
