Flames of Devotion / White Flames AI condition?

[Makro]

Hi.

I'm trying to build a ranged Kind Wayfarer/Troubadour healer with dual blunderbus, but I find myself running into some annoying AI condition problems. What I want to do is to check if any on my allies are hurt, and if so, then shoot an enemy with FoD in order to proc White Flames around the caster. The problem is that FoD is target-able on enemies only. The best I can do is to check my own health and if the paladin itself is hurt, then I can use FoD on enemies. But how to check this same thing on allies? Right now I've just set a condition that I'm using FoD every 8 secs (due to shared flames cooldown), but this is far from optimal. Not even the "more ai options" mod seems to provide a solution. Big thanks for any help!
