In beta, if shocked Vette enough, she would eventually go insane and commit suicide by throwing herself out the airlock.
Why would anyone want to do that?
Even on my DS SW, I shocked her a few times at first but I couldn't bring myself to do it anymore.
IMO worst are Skadge and Akaavi.
I haven't recruited Skadge yet on my BH (currently in the process of completing Belsavis) but he's annoying already so I'll give you that. But you shut your mouth about Akaavi, she's awesome. I love how she's essentially the straight man to my smuggler. And she's puts out some pretty nasty dps too.
