We allow heal as a ranged non-action to give a health status update on NPC hp, if they're barely injured, about half health, fairly damaged, or very close to dead. And on foes that are felled, to tell if they're dying, dead, faking (vs. bluff), etc...
Makes it slightly more useful. I'd also like to incorproate that skill trick that uses it as a sub. for crit confirmation rolls as just another general use application of the skill.
I've also considered in the past tying the amount healed by cure spells to the spell and a heal check, rather than the spell and CL.
