Right now the director can hit you with a brutal, grueling fight that drains your resources (boss, 4-6 specials, armored patrol, and horde all at the same time), then do the same thing again around the next corner. It’s a death sentence for a run on any difficulty, is not fun, and makes players feel like RNG decided the outcome of the run rather than player skill and effort.
The director should keep track of how hard it’s beating the players down and have a cooldown after sending big events. Even the best players could use a little breathing room after surviving an absurd battle with basically every enemy in the game. At the very least the aforementioned run-ending combo should only occur (at most!) once per run.
