I have the following mastery setup.


As maxed out Liquid Courage mastery removes 0.6% health per sec and maxed out will power generates 0.7% health per sec, doesn't it mean that I should be having health gain always more than poison damage??
If you see these images below,



In case of Cyclops, the liquid courage damage and will power health generation are equal. In case of Thor and Iron Patriot it's less health generation compared to liquid courage damage. How can this be possible?? Am I doing anything wrong?? I want to utilize this mastery setup and would like to know how get 0 damage with help of will power. Any suggestions on the same will be helpful.
