What would you do if you were in Daniel's position?

Well it can dissolve a pig carcass, that should speak for itself.

Well, being that it's just a game, I doubt they would really care to make an animation for partially dissolving the pig and did this out of simplicity.

Flesh is a lot weaker than steel. That's why we use swords to cut people. That said, I'm sure acid would work just fine against the gatherers, even if it doesn't work that great against a strong, steel lock.

Yup, I was expecting someone to say that. Actually acid reacts more violently with most metals than it does with flesh.....just the way chemistry works.....physical properties (like hardness, density) matter much less than chemical properties do.
