Since this weapon came out with AoM, this is the 2nd really hard nerf. First one was about 33 %(?; can´t remember exactly) to flat bleeding damage, now 80 % nerf to two skill modfiers.
I tested it in SR Shards 75+; it really hurts. And I don´t really see why this has to be this harsh. 50 % (150/3 sec) or maybe even 66 % (100/3 sec)…okay, if you think this is necessary because of too much damage e. g. in Crucible, but Bleeding builds are not known to be op in SR.
Or perhaps nerf only the skill modifier to Whirling Death, because is already has very good bleeding damage, but Belgothian´s Shears?
