Because really. Extra damage to shanks? On a [i]rocket launcher?[/i] Who in their right mind would look at a perk like this and think "hell yeah, this will be really useful"? So yeah, spanking. I'm thinking a bit over the knee, maybe take it in turns. Who's with me? edit: It will not be useful against that 'shank boss'. It's a pitiful amount of damage with a large delay on trigger that will mean absolutely nothing in any fight. Also, not only is it useless, but it takes up a perk slot. So shush.
