• Shattering Throw: When the shield hits an enemy, it splits into 3 small fragments that bounce between nearby enemies, dealing170% weapon damage as Holy to all enemies hit. (Up from 50%, damage element now specified)

You shouldn't grab your sources from datamined information. On D3 main page it does not state "damage element now specified" If you have been using shattering throw this whole time then you should know that it has been holy damage pre 2.0.5. So yes it was nerfed...
