So I personally had my doubts about kraken club for WHM so I went and did some numbers on some dynamis mobs since that's probably the most relevant stuff a WHM would melee on. Used Red Curries and Dia 2, /NIN because I didn't think about /DNC, but it won't change much weapon comparison-wise. First set is with STR Magian offhand, second Kraken Club.
I guessed the WS Base crit at 10/20/x so base crit for hexa is 30% here, factoring gear and merits.
Don't take these sets as optimal, I know I left brutal on for WS when I could have used Ghillie+1.
