Well here's a update and this is was a few minutes ago. but played a mission on a fistful full of sand, lost as sooma and tried it again as loaht. all i can say is that i now have a score of 10.1 right now.  Holy freaking crap it had my jaw drop as i didn't think I'd achieve it.  i was taking out little grunts, as well as elites and dominating the antagonist. without even using the beast form,  i didn't use it till the very end and only got two kills. it was funny but i was still rubbing my eyes to make sure i wasnt seeing things.
