A while back I tried using Divine Healing in my hero monks skill bar. Initially I didn't pay much attention, but eventually I wanted to know if they were using it. I don't think I ever seen them use it tho. Eventually I replaced it and forgot about it.
So my question is do they even use party heals? If they do, what criteria is required for them to use a party heal? I notice that with normal healing skills the hero will not use it unless the amount of healing the skill provides will be fully utilized (or close to it?). I have some hero rangers that use vampiric weapons and outside of combat a monk will never heal before my rit does. From observation, the monks healing skill is better and heals for more than my rit hero's healing skill so the rit is the one who always tries to heal my rangers first.
This leads me to think that a hero skill will not be used unless it can fully or mostly utilized. But as far as party healing is concerned I heavily doubt that the entire party would need at least that much healing before the hero used it. So I'm guessing maybe half the party or more needs at least that much healing in order for the hero to use the party heal. But I'm just guessing based off of previous observations of how heroes use skills on one target.
Can someone shed some more light on this topic of heroes using party heals? Is it even worth it have a party heal in their skill bar? I left it alone for a few years, but now I'm revisiting the idea and I'd like to understand it better.
Thanks for your time
