I'm a big believer in using ACLs to intelligently preclude reflection/amplification abuse, but wholesale filtering of

I also think that restricting your users by default to your own recursive DNS servers, plus a couple of well-known, 
well-run public recursive services, is a good idea - as long as you allow your users to opt out.

This has nothing to do with DDoS, but with other types of issues.
