They nerfed for multiple reasons. Fore most is the fact almost no one uses pulse rifles. Not everyone likes them. Personally my Bad JuJu is the bomb. You based your main reason for the nerf of AR was the use in IB. So you put a bounty on there for head shots with an AR. Fine you want that, great you got it. When you go into combat I am going to leave my best guns at home right? That is like taking a yearling in the Kentucky Derby, while you have Man O War ready to run. Bungie's reasons make no sense, you want us to use pulse rifles? Jump them up, want us to use shotties? Fix them, just don't cut what people like because that is not the way we intended you to play the game you bought and paid for. Just saying.
