Basically what Freyyy said Sks affects Drks to a degree but not enough to warrant any kind of big change compared to Det and Crit I have 850 crit and 740 Det on my Drk with about 600ish sks I tried fitting more Sks and my dmg was lower than if I actually had the 60 det and 70 crit I was missing. On the page of Blood Weapon you need so much just to get 1 more GCD in Blood Weapon and that's sacrificing even more det and crit to meet that threshold.
