Is it ok to use this program to play Guild Wars 2? I've just been seeing people getting banned for using it on Reddit, and I use it occasionally when I don't have the game installed. For those who don't know, it is a legit program from NVidia that allows you to play games over a cloud streaming service. The games on there have to be approved by their publisher, so ArenaNet have, quite recenetly, allowed Guild Wars 2 to be played over the service, but are now randomly banning people for using it.
