An extra tip for pulling, try not to pull with attacks that can knockdown, or kockback a foe. I have a lvl 41 ar/dev blaster and when I pull with burst I have more succesfull pulls then when I pull with slug.
Another good tactic I use for pulling, or even killing a mob within a group. Turn on SS, CJ and Cloaking Device... move within burst range, SS back up and right before you get out of range take a jump and press attack button. Due to SS and CJ you draw your weapon in midair but keep finishing your jump and you land out of l.o.s. firering your weapon. In most cases the foe doesn't know what hits him, until you get back in his range again. If you wait it out a bit, the agg drops.. and you can do this all over again. Might take some practice, but it works =)
