this begs the question, why not?
random bgs don't matter, they don't affect rating and unless for some bizarre reason you are obsessed with your w/i ratio. i can't really see why occasionally getting rolled by a premade is such a big deal. its happened to me, it happenes to everyone, i don't get why people are so insulted by it, you just accept it as part of bging and move on. and its not like you don't have the exact same tools at your disposal to do the exact same thing.
maybe i just hate saying no to my friends
