Before engaging a mob, I'd always toss a Vigorour Spirit on myself. For 30 seconds, it sits waiting for a Release Enchantments to provide a 33 point party heal at 14 Divine Favor per enchantment. If a larger party heal is needed, a 5 energy Guardian followed by A Boon Signet, then release provides a 66 point Heal Party for 10 energy (and returning 4 energy from Boon Signet). Vigorous Spirit can naturally be tossed around warriors, assassins, and rangers to heal 12 health per action.
Reverse Hex briefly acts as an enchantment, so if I'm hit with a hex it will add onto Boon Signet and then the following Release Enchantments. Because the build isn't too energy intensive (and it's PvE afterall), using an extra 5 for Reverse Hex over Remove Hex or Holy Viel didn't seem like that bad an idea. Although the added effect of damage reduction is somewhat lessened if the party member is under fire, so trying to hit a Boon Signet before it triggers is unlikely. Might consider replacing it with Holy Viel, just so I can use Boon Signet first without having to rely on my target not being hit to gain the benefit of the enchantment. Not to mention that I can't use it on a target that doesn't have a hex already on them. Depending on the area however, I chose to use Mend Ailment when conditions were more rampant.
Signet of Devotion somehow finds its way into any build I have with a higher Divine Favor. Free heals are always nice, even if the build isn't too heavy on energy. I'd often swap it out for Rebirth when with a PuG, or a full guild group when I knew most situations would be smooth and the extra 94 heals would not be necessary.
Protective Spirit really goes without saying, could also be used pre-combat as another enchantment just sitting there for Release Enchantments. 14 protection prayers meant 22 seconds, on top of the 20% longer enchantments on my weapon.
Guardian, again works well for most areas and is a cheap spell to throw on for Release Enchantments.
Aegis allows every target to provide +2 energy from Boon Signet, and before it wears off can be released to cover some of the damage that snuck through the 50% block. In most cases, I'd throw a guardian on myself and then release Aegis, Vigorous Spirit and Guardian for a 99 point heal. But not before using Boon Signet to return 6 of that energy.

It's been a pretty fun protection build to run, just a matter of using Boon Signet on the best target whenever it comes up. One might also consider using Order of Pain or Dark Fury to fuel Boon Signet, the only problem being that they won't provide heals with Release Enchantments.
