usage of the superative (worst)

[Sweetpumpkin]

Hi all,

I hope the attack was less severe than the last one, which was the worst ever in history.

Please focus on the last part: which was the worst ever in history.

I didn't read Alan's discussion, but I am sure that he would not object to your original sentence ('the worst ever'). 'The worst' is a pronoun itself, relating back to 'attack'.
