And that's great, for your group. A problem arises when people try to make this a universal rule that "should" be applied to all tables. I can't tell you how many "advice to the DM" videos and columns I've seen that say, as an absolute principle, that the DM should always make sure players fear for their characters' lives, because it will make the game better. That's simply not true for every group, mine being exhibit A to the contrary.For my players, it's about there being a risk of losing the character. They invest in their characters and want to feel like they can lose it all if they screw up or things go very badly for them. Without that risk, they feel like the game is too easy and that reduces their enjoyment.
