But this is literally the problem. No one healed. No one who understood the game math ever took Cure Wounds. Instead, they took Healing Word, waited until their ally was down, then bonus action got them on their feet so they could misty step/fireball/smite ect. This is why people got furious at Healing Word, why people constantly demanded an end to pop-healing. Because it was the only effective healing in-combat. The only healing strategy that actually worked the vast majority of the time.
It doesn't make anything "too easy" again, that fight where my cleric was constantly healing my allies every single turn? It was nearly a TPK. And because of Mass Suggestion, I didn't have an option beyond healing them. But because my healing was actually effective, I was able to keep everyone up.
So is it magic missile or burning hands you think is overpowered compared to a 2nd level spell? Because those were the examples I was using, to showcase how utterly deplorable Cloud of Daggers was. Which of these 1st level spells needs nerfed in your opinion?
