Good afternoon, I started playing my unholy DK, she is level 100 and is using BoS. Now I am a little stuck on if I should be prioritizing scourge or festering strike. Now I know if I have either 2 blood or 2 unholy runes I should always festering, but when I have death runes available, should I just use scourge for them, or festering? Which is more important/higher dps.
