s assault+ s defender dualskill sr is a good option for a long time for almost everyone. We will have fire bow and something dark (lance?) with this skillset too. Another option - hime weapon like Hastur's orb (L defender+ S assault), that is great even LB0.
BTW, Kuyuki is not reprinted on DMM yet, but we have another Typhon on DMM reprint right now - only in 1 year after previous. I pray about Garuda's another reprint because both weapons are amazing, not like Typhon's.
Kuyuki bow FLB should be L defender+ s assault, like Sphinx hammer.
