The SSS dummy should explode and kill the player if they fail to defeat it in time.

I was obviously implying that they don't intend for you to challenge it before 205, so mentioning that you can't complete it with less gear is irrelevant.

While his example may have been extreme, we cannot say that gear is entirely irrelevant regarding SSS. An i205 DRG will dps higher than an i215 DRG with the same rotation, for example.
