I see a link-filling attacks with some regularity; but again, what I'm saying is simply that they aren't as prevalent 
as they used to be, because the attackers don't *need* to fill links in order to achieve their goals, in many cases.

That being said, high-bandwidth DNS reflection/amplification attacks tip the scales, every time.

This is a very important point - determined attackers will observe and react in order to try and defeat successful 
countermeasures, so the defenders must watch for shifting attack vectors.
