It has ludicrous damage, but you have two shots and you have to land both with a reflex sight. It takes ages to pull out your secondary, so by the time you finally get around to maybe getting one hit to land and having a secondary to finish them off, you're already fucked.

I'd rather have Twitch, Blackbeard, or Buck (In that order) if I want a rifle. Not Dokka or Viggle.
