Funnily enough... On a 27 STR 40 DEX build, you can still pull off 731 AR while 2-handing with the WA buff. That's an extremely cheap investment for 700+ AR. A yes, it's split damage, but so is the DGS, buffed Lothric Knight Greatsword, and buffed Mad King's Crucifix. Compared to Yhorm's and Ledo's, this thing is more stamina efficient, and it has a better movepool.
Even more interesting, a +9 simple infused offhand will yield more than enough FP regeneration to cover the cost of the WA's buff; allowing for a perpetual 731 AR.
...And hysterically enough, courtesy of this thing's high Fire damage, you can easily riposte for over 800 damage in PvP, no Hornet Ring required.
Ahhhh... My beloved Simple Llewellyn Shield and Lorian's GS... How many edgelords have we rekt?
