Warrior %/s (KMS You & I + GMS Unleashed)

I'm struggling with a new equip upgrade. unbuffed pic below. I'd like to ignore the 2% str neb.
weapon empress scimitar
unbreakable will 40%
Leafre Codex 30%
Gollux Set 30%
light wash L2 15%
Rhinne's 10%
BTamer card 6%
3 Pirates card 6%
missing 10% shrugs

looks like 0.82114 = 1 - (1-0.4)*(1-0.3)*(1-0.3)*(1-0.15)*(1-0.1)*(1-0.1)*(1-0.06)*(1-0.06)
vs 0.91862 = 1 - (1-0.4)*(1-0.35)*(1-0.3)*(1-0.3)*.... FIXED ty JoeTang
and i only have one additional 9%atk potential besides the unique emblem

 Spoiler

keep the ignore? or just cube for +21% atk? secondary option, keep ignore, and recube the unique one to legendary

i think this is enough information o_o
