Only if you REALLY want the 4 piece bonus, which is currently bugged.
Nobody seems to be sure if Scavenging actually improves your drops. It may even make your drops worse.
20% Health on Kill is nice, but other sets offer much better.
Over all, I find it's the least attractive of all the sets. Sentry and Strikers are utterly destroying people in PVP and owning PVE. After Tactician's, those are where my efforts are currently.
