It has always sort of baffled me that the SE servers are okay with hosting a download for the test server (Which is also several gigs of files), but they can't be bothered to have some sort of direct download for the game itself. The key is what we're paying for anyway, it would be really nice to have some sort of direct download instead of having to resort to shady third party sites (IE torrents).

Until then, torrenting for the game files themselves or getting them from others in the community remains the only way to reinstall the game on a PC.
