I normally pull with devour strength, do torture after that, and if they're close enough and I'm not going to put myself in a bad position to get other aggro, I'll go ahead & shadow step/backstab, and then continue with melee attacks.......if it seems a strong opponent & shadow step is ready to go, I'll do it again cause it's just damn good fun, and the backstab takes a big chunk out of their hp
if the mob is out in the open and I won't aggro others, I'll sometimes start with the shadow step just to have fun and get a big hit right away.
a quick edit: if I do get aggro from 2 creatures and it seems like sure death, I'll fear one to try & work on the other, and if they come back before I kill the current, I'll fear them again
