Shaman/Necro stacking

[HippoNipple]

its really not that big of a deal even if they dont stack, the necro will be using heat blood line of spells, along with the clinging darkness line, and allure of death (hp dot). So even if the disease/poison dot's don't stack you can easily work around it, and you can test if the poison/disease dots stack really easily, just go try it.
