If you can get or ask for an Assist so you can "fix" groups for PoH, do it. It helps a ton. Group all the melee and tanks in group 1, and the ranged DPS and healers in group #2. Usually most ground based AoE dmg happens in an area either at and around the boss or off in the distance somewhere:
1) If it's at and around the boss's hit box, PoH/CoH group #1
2) If it happens at a distance somewhere but two or less people are only hit, use direct heals (if you're one of them, hit the other person with Binding Heal)
3) If it happens at a distance somewhere and three or more people in group 2 are hit by it, then you can PoH that group.
Keep in mind that if you set up groups where ranged DPS and healers are together, a healer's reflex is to heal themselves first, so even if 3 people got hit and all three of you are healers, you're better of ignoring the other two (unless they're dangerously low of course) and Binding Heal someone in group 1.. especially a tank b/c you can refresh Renew with Serenity chakra.
Keep in mind that Binding Heal in general is all sorts of awesome b/c aside from the HPS and HPM wonder, it also gives you a stack of Serendipity which saves you mana on your next PoH or Gheals. Synergy =)

You can also center the spell off of mob targets, including bosses.
