So... now fighter guild skills work against all vampires, so enemy players now have a 9% damage boost against them, gain 9 ult a kill, and can one hit with all the skills in fighter guild skill line.
Whilst Vampires now cannot feed/ envigorating drain on any enemy player anymore(since update).
Damage mitigation passive which is the only thing to counter this B/S does not work against enemy players, and even if it did, would not have a great enough effect to be even close to balanced with this grand idea of an update.
