Agreed, but there are lots of high-CR enemies that are indeed poison immune. Maybe the poster you're responding to has encountered a lot of them.

Giant Poisonous Snakes + heavy obscurement (blindsight) is indeed awesome. Fog Cloud, Sleet Storm, whatever.

I'd say Pack Tactics is still better than a higher to-hit against higher AC enemies, but yeah Giant Poisonous Snakes are tankier and have higher damage.

If you are looking for damage too, shoutout to the Stench Kow. Common damage resistances, same to-hit as GPS, single roll for very good damage provided you can charge and AOE poison. It doesn't have the tankiness of the GPS but 8 of these charging can unleash hell.
