You assume that deathblow is equal to ABS.

That assumption is false. Brutally, horribly false. Additionally it is an over simplification because play a non flying/concealment villager and learn how scary 2 peolpe with trip suddenly become (not even very tough people).

You seem to both akowledge the balancing factor of villagers (they die a lot) without comprehending the extent to which their restrictions truly are crippling.

Look through villager PBF's, they don't get super duper high PK totals, they do get absurdly high pk death totals compare to non villagers. If they really were OP then that wouldn't be the trend. This ain't any fallacy, it is objective performance tracking.
