This bug has been happening ever since they fixed all professions F1 abilities functioning with the rune of vampirism proc. Although for necromancer, the fix has hurt the power necro, due to the fact vampirism runes are almost always the go to choice for zerker/marauder builds in this meta.
You can notice that when I use my deathshroud, roughly 3 seconds afterwards I am forced out causing us to lose even though I had full deathshroud.
