Game Design Make the Golem Room in TCC not fail if there's only one person

Hello, I obviously understand why the raid fails in other rooms that are just necessary to be done with more people, but Golem Room is possible with just one person, so why does the raid just end when there's only one?

It's especially frustrating when there are only 2 people alive, like 10-15 seconds left on the clock and one of them dies and the raid just ends, even though the room was completely completable with just that one person.

I don't see a reason why this shouldn't be changed, cuz even if that last player isn't up to the task to handle rest of the room alone, then he will just die and the raid will end anyway, so I don't see any downside to this, even from a difficulty perspective.
