Strictly for bird merits, I see people mention that this is good but all the polearm discussion is centered around Tomoe and Engetsuto.
Is this a worthwhile weapon and how do you get the most out of it?
With low delay (396) do you still stack the 29 stp (assuming 5/5 merits) for a 6 hit, or do you settle for a 7 hit?
Mainly my question is what's the best setup for this weapon assuming it has a place in merits? My gear is mostly limited to AH pieces except for a few necessary items, rajas, brutal, b.haidate and swift belt, and a few other easy to get items. So, a few options that I could come up with: sam/drg, 25% haste, 7 hit, (can also get 7% DA from brutal and pole grip, since i wouldn't need rose strap) or sam/war 20% haste, 7 hit, etc.
Realistically I can't see a 6 hit with this weapon until usukane feet and body, maybe askar body and usu feet but I'd hate to loose the acc from hauby. And I'd hate to have to get askar body.
