well with lategame gear andariels will probably heal you to full with 1 or 2 hits. So i understand this concern. But on the other hand we have stuff like
Starlight Aspect (Legendary)
Gain [10 - 20] of your Primary Resource for every 25.0% of your Life that you Heal.
imagine going for very high hp, so surviving a couple hits is possible and leeaching yourself to full in just 1 swing. I think this combination could be insane in high nm dungeons. In normal circumstances this aspect sucks, but here it might have home, a very op home.
