That's the BiS I came up with by iterating Acc and Crit by 1 point each, taking care to skip impossible values and then calculating the weights using 535 minimum accuracy and the default weights. I also avoided Flint Caviar. Note that this might very slightly over-value SS, but only slightly so. I'm also way too lazy to work out a crafted BiS, partially because I don't have a better tool than ariyala's site and partially because who could even afford it?
