Blessed Life (BL) can account for a major part of our Holy Power (HoPo) generation, in some encounters. There's some boss abilities we can't avoid, and generating that extra HoPo can be nice, so I’ve with the help from eternalwhitemoon and Simca made this list containing which boss abilities that generates that extra HoPo. If there's anything that should be corrected, please write it as a comment and I'll make a change.
If you're using web logs, you can use following code to indentify what abilities causes you to gain HoPo:
