959 crusader strike on rogue with wings is the result of sanctified wrath since the rogue has PWS on, so you are bypassing 50% of it, in other words, you actually hit for 1918. He also has 3% reduction because of renewed hope and 10% reduction because of inspiration. Not to say it's great damage anyway.
Regarding the hpal I have no idea but it's possibly a blessed life talent proc. Or maybe you're right and damage is broken, :-)
