I couldn't disagree more. There had to be a way for scum to take out threats/confirmed townies otherwise with the level of protection town had they'd have no way to kill their targets. In the end only a single role could do so and even that only after another role which didn't want to kill players randomly had died. I think it's fair. White Queen's anti-claim was effectively the only anti-claim mechanism - claiming was allowed to assist the town, but there had to be consequences towards it.
