Far superior than BKG and i don't understand why so much love for BKG, i understand the BKG R2 is cool but being unable to buff the weapon just make Glaive far superior.
Heavy is the best infusion, this weapon is hight dependant of the WA, if you are not the type that use WA, just use the Winged Knight Halberd or Crescent Axe (coz at refined 40/40, with WA you gain more AR than normal Glaive)
