For me regular Ice shards non raiment build from maxroll but with maxed Frozen orb + Frozen orb aspect works fine (take points from Nova etc.) . Also burning reduction instead of blaze on amulet.
You dont need Raiment instead 4 x defensive chest+pants and swap obedience for Everliving.
Frozen orb ench procs often and chills entire screen thus activating Everliving 25 % DR.
Also in Boss fight it allows for much better DMG than pure shards, as Shards ench is useless there, and also staggers quite fast.
It allows for a bit of ranged playstyle and I like Frozen orb sound/aesthetics.
