Guild Wars 2

ive played a mark/wellomacer since the beta but ive heard that healing power may affect mark of blood and my wells when they siphon life if this is true would it be effective to add healing power gear as a semi support/dps build?

Healing power will effect mark of blood because healing power boosts the effects of regeneration. (0.125 ratio applied per second) The well siphon (Vampiric Rituals) is not affected by healing power, to my knowledge. The damage ticks applied by Vampiric (the minor trait) are affected by healing power, but only slightly. (It’s something like 6 health/tick per 1000 healing power) Of course, the heal from well of blood is also boosted by healing power.

I can’t really comment on if it’d be useful. I’m tempted to say no though, since you get a lot of healing just from the base values, and you sacrifice a lot of damage to get noticeable healing power.
