As someone who has mained BRD since 1.0, I don't think there's any particular single nerf that could ruin the job like so many people in this thread seem to think. Even if Blood for Blood is lost, you'd still have all of the other abilities you have to boost damage. If Invigorate is lost that just means better TP management and honestly there aren't too many cases where TP is a massive problem such that the loss of 300TP every 2mins will make or break it.

It's my gut feeling, which of course has the chance to be wrong, that BRD won't really suffer or be utilized any differently because of this "nerf".
