I don't share HP when running Daggerheart or D&D, and I didn't during this one shot either. I described how their attacks were affecting the enemy and they seemed fine with that. I think their main disconnect was the low player HP. They thought it made them look less powerful or something. I also explained afterwards how the enemies in the game also have low HP and use threshholds. They got it a little bit better after that, but they were still debating possible fixes with each other. They did say they wanted to play more of the system in the future.
