There is one thing that bugs me about frost presence and blood presence, the fact that blood has the 4% heal from dmg when frost would benefit so much more from it. If they swapped the 4% healing for the 15% spell dmg reduction it would sill benefit both presences the same if not more. Blood already has a lot of heals with the talents they get, the 4% is nice but it would greatly benefit frost more than the 15% reduction in spell dmg. so you would have. I have looked at the amount of healing since the buff to 4% and on average you gain 300-400 health a hit (non critical), so you tell me what u think?
Blood P
15% more dmg
15% less dmg from spells
Frost P
80% contribution from items
10% health
4% dmg done as healing
