Examples are Dark Animus' Interrupting Jolt, you HP before every cast and add a lot of security to the healing. Lei Shen p3 is similar, use it either before or after TS depending on the raid's health.
From a damage perspective HP has the ability to be useful, casting it off yourself for the 5 target AoE. That said though I'm yet to see a fight with such consistency and emphasis on adds that it'd be superior to boss DPS. That of course, is subjective to your own raids needs.
Only fight I use LH on is Ra-den because with the levels of vengeance you play at it's a huge raid CD on a minute CD. Seems more useful to just say '300k veng hammer is down' as part of the CD order than to splash out the smart heal in one chunk every 20 seconds.
