FluffNStuff, your work always impresses me.

I find it interesting that in a game where just about every mechanic surrounding health works as a %, that this would be a static number. My immediate thought was the viability of stacking defense when playing as more of a support role (using Curse, Dark Binding and Vermin Swarm), to allow for maximum casts in a taking-no-damage senario (in a group, for example). Especially given that these 3 "support" abilities don't scale with the damage (and by extension attack) stat and stacking health is moot for a more ranged vamp.
