I think that there must be some new content in TTK that even with a underpowered BH, fireteams would be able to sit back and crush w it. I can see that as a solid reason. Which raises the question, why not build content that counteracts the gun's abilities? Because its much easier to just nerf it. For the record, I have no problem leaving my legendaries behind. I just don't see why they bothered unless there is very specific content in TTK that the BH will continue to destroy even at 331/365
