There are numerous ways to make Boss monsters resistant to save-or-die attacks. Kromm just went through a specific example, our hypothetical Evil Knight.

It's the same 'problem' as having a highly skill fighter using, for example, Feint / Target Eye combos, letting them reliably one-shot an opponent every second. You just make sure that some fights have Zombies or Golems or flying witches or something else that isn't vulnerable to their one-shot fight ender.
