While their is truth in that statement, in this case you already paid and this is the quickest way to allow Microsoft to dump all outdated forms of Windows at once and cut costs on outdated products. Now anybody getting Windows will pay, this is nothing but a win for Microsoft.

I've been playing WoW for the last 5 years with a video card that is on the unsupported list. Been running fine besides one or two surprising things (e.g. I couldn't see the telegraph of the second ceiling collapses on Twin Ogeron in Highmaul. Just didn't render). WoW doesn't actively refuse to run on 'unsupported' environments afaik. They just will stop testing and ensuring that it does I guess.
