Cometkaze

Came up with this for amusement. Its working in maps currently, but i figured i'd ask here for thoughts on ways to improve it. Its a slower clear speed, but my survivability is pretty good.
Im using skeleton warriors, from gem and sceptre, as a shield wall and comets from cast on minion death to clear.
Unearth - socketed with corpse conservation, mobility and bludgeon is the primary attack. It summons more minions for comet triggers while also knocking enemies back for survive.
Skeleton warriors(gem) - socketed with Infernal legion and maim to force trigger comet.
Skeleton warriors(sceptre) - socketed with heft, discombobulate and feeding frenzy.
Hypothermia, bone cage and mana tempest are the other skills currently in rotation.
