With healing being nerfed (and then buffed again, but still and overall nerf compared to the original system), passive skills that require a hero to be at full health are ridiculously hard to trigger. Not to mention, all these new heroes and hero reworks seem to enjoy adding abilities that do minimal amounts of splash damage.
I think a simple fix would be to just make such skills work at 75% Health or above, but you know what would be even cooler? Making these types of passives work like reverse Savage Fury's! The more health the hero has, the stronger the skill!
For example, Julius would get a 1.25x boost to his damage when at at least 20% Health, and for every 10% more Health he has, this boost is increased by +0.25x! Or for Augustus, he heals all allies a tiny bit each turn as long as he's above 40% Health, but the healing gets stronger and stronger the more Health he has!
Oh, also, can Augustus' 'Lay on Hands' skill be changed to function like Dagrund's Energy Rune? That is, if he uses it on someone else, he still can be healed and cleansed by it? Obviously casting it on himself would make it heal even more, which could actually be used in your benefit if his Spread the Wealth passive is changed to work like I described!
