I have IB. Since i got it, it's very hard to replace it with anything. Maybe murmur at times. I have invective too and love in in pvp. With this shotty buff coming(or is it here???) i think invective will come out to play a bit more. Saint 14 plus invective would be fn awesome. Missing one of those tho..... Other reason? Almost every situation leads to a quick death when ur in that close for that long. The range on the shotgun is terrible, at least ones i have owned.
