I don't agree with this.

Normal traffic on a well setup network should not include large numbers of 
fragmented packets. But I have seen too many networks that fragment almost 
everything as a result of there being a hop that goes through one or more 
tunneling layers that lower the effective MTU (and no, path mtu discovery does 
not always work)
