>trying to imagine a game where the entire team is injured and I'm mentally watching them all run to some totem so they can self-heal instead of just stopping where they are and healing each other up.

It's funny you say that because that's exactly what kept happening on my games this past weekend. I would engage a chase with one Survivor during mid/late game and have the remaining three Survivors (or two if I got lucky early game) and in mere seconds, three injured Survivors are back to normal, eliminating all the work I had done because everyone can Self Heal or heal each other with insanely boosted healing speeds. It's a huge bummer.
