Dear SE,
we do understand you don't have the technical skills to build a decent patching system (scaling servers, optional P2P, win32 interface, delta patching). But it's ok. I don't have them either. Really, it's ok, Don't try to improve it anymore. Don't apologize anymore. But please, consider investing in an existing patching solution. This would be a very potent investment, as it would ease the use of all of your games at once. I'm also pretty sure it would cost less than trying to build something decent from your actual system. And it would make everyone of us happier.
We are not angry with you SE. But now, please, it's time to be reasonable and do things properly.
Cheers.
