Ravenous Hunter Heimerdong
I have been trying this, and it seems pretty good.
Heimer is a master of shoving wave, and setting up camp at enemy tower, until it is gone.
When using Ravenous Hunter (bottom left Domination tree) I am always full health.
After using it for a while, I can't go back to other secondary runes, because I'm so used to ignoring poke, and healing it right back.
Why I ask don't more people use this on mages in general?
and you'll have a perma shield while laughing at enemies as you poke them to death. :V
