Datamining error. CS/HotR are certainly not going to stop generating Holy Power.

Description : $?s85673|s85256[An instant strike that causes $sw2 Physical damage and grants 1 Holy Power.][An instant strike that causes $sw2 Physical damage.]
The "Description" part is the tooltip, and that string translates to this:
If the player has spell 85673 (Word of Glory) or 85256 (Templar's Verdict), use "An instant strike that causes $sw2 Physical damage and grants 1 Holy Power" for the tooltip. Otherwise, use "An instant strike that causes $sw2 Physical damage."
We have Word of Glory, so we'll fall into the first category (all paladins will, obviously). The datamining sites occasionally don't register those conditionals properly, and thus end up indirectly sparking panic from people who blindly trust datamining (or have more paranoia than common sense).
