The High Aldwin
Ironically I think Death Saves are probably the most realistic mechanic in D&D human response to wounds is all over the board.
I don't mind the death save mechanic, but we add CON bonus to the roll. Trust me, if you compare a CON 20 to a CON 5, the CON 20 is much more likely to self-stabilize. Just to be clear, this is not a CON check or CON save, we just add the CON bonus (don't want things like Remarkable Athlete also affecting it).
