Hi chrome !
Actually i think it VPN services that can chains servers to get better a better ping toyour final destination server.
The point where i'm blocked is i have to authentify with my WTFast account to get access on all servers, so i can't just add the proxy on field setup of Stealth

I can't use WTFast with client.exe cause Stealth deal everything with server too.
sorry for asking i know there's no support for this, but it may help many people who play on oversea servers

.
(forgive me for my english^^)
