It sucks because it`s not a crit. based WS like the top tier Empy weapons. I do agree though, we kind of got boned with the WS. Rampage does kick some serious ass in Abyssea though.

People have gotten up to 5k without brew using:
-Atma of the Lion
-Atma of the Ultimate
-Atma of the Blinding Horn

Apart from that, stack MAB, STR and MND for it.

Mind you, that was with 300% TP and using an Ascetics Gambir. It still flogs any number i`ve seen out of Primal Rend though.

It`s also your best option for brewing and will benefit from capped stats much more than Primal Rend because it has two modifiers.

Out of interest, what setups have you guys used for Bukhis? 14 wings down so far for me
