The whole point of the discussion has been that prior encounters during exploration be it traps, hazards, exhaustion etc have no impact on future effectiveness. But you seem to be saying any impact on future effectiveness is critical problem?If it has some impact on the next fight, the next fight is going to be harder. And the next one harder still, since more resources will need to spent to defeat the harder battle. Eventually you will reach the point that the fight becomes impossible. Death spiral is will always happen eventually.
So they cannot run away from a monster, so they die.
So the monster takes one more round to die. And the party dies.
Anything that reduces effectiveness means the subsequent battle is going to consume more resources. If, due to simple bad luck, an early fight leads to a permanent injury, the party won't survive the final challenge. Or the difficulty was set so low that there was never any real challenge in the first place.
Parties are made up of multiple characters. I don’t believe that minor effects from lingering injuries has the kind of impact you’re claiming. Certainly not in the 5-8 encounters max that a typical few days of explorations and dungeon crawling would have.
