melee summoner(domi blow+herald of purity)

At this moment, my build is https://pastebin.com/7rxmEG3d . How would you guys improve it(i am running out of ideas).

maybe this would help you out https://pastebin.com/GdKbnHWZ
I planned around life regeneration, to have at least 1 thousand life regenerated per second, and some life leech. 8 thousand life, dominating blow minions and those minions from herald of purity. adding the damage of all minions it would be around 1.5 million shapper dps. it's a pure physical damage build, a little different than most ppl do these days with a bunch of auras and elemental damage.
