Sinister Calling percent damage bonus has been bugged and isn't multiplicative. This means it benefits Hemorrhage more than Backstab, because adding 10% to 180% weapon damage only takes it to 190% (192% with opportunity?) instead of 198% (180% * 1.1).
In comparison, Opportunity and Aggression are multiplicative. Opportunity increases Backstab from 150% weapon damage to 180% (20% total damage increase, as the tooltip suggests), and Aggression increases Backstab from 180% to 207% (15% total damage increase, as the tooltip suggests - can't afford to get this talent as subtlety).
