blessed signet returns 3 energy every 10 seconds, per maintained enchantment (assuming you have enough divine favor). since 1 energy every 3 seconds is 1 pip, 3 energy every 10 seconds is .9 pips
which basically means that blessed signet reduces the cost of a maintained enchantment by 90% - from -1 pip to -.1 pips.
but. if you use mantra of inscriptions, you can further decrease that amount... and then you would actually be getting energy per maintained enchantment.... would it work as energy management on a monk? maybe just put say 3-4 enchantments on people, use mantra of inscriptions and channeling (just as an example), and then maybe that would work as a non-elite energy management?
and note you dont actually have to use life bonds.. there are plenty of other enchantments to throw around (like mending

any thoughts?
