Yeah, it's underwhelming when you first get it. The +targets legacy makes it way better. You can get nearly guaranteed crits off it with a decent amount of crit chance and a big crowd.
But, even then, Devastating Blow still has its place. It does have a higher innate Critical Magnitude, so I still rely on it whenever I only have one target to deal with.
