ive already calculated this b4 and it comes out to a caddy with +3 hs +3 concen +3 smite would be better than anything else, in damg terms by a few hundred, as in silence/other + max fanat u gain a more flexable weapon choice, the only thing that makes beast a bit better is cuz of the versatility to give concentration to others or in 1:1 keep on convition to use an foh advantage but you must be quick on hot keys.

simplified: not worth building your char around 1 item, cuz it makes you weaker to elemental attacks and such
