If dipping continues to not use an expendable resource, like alchemist's fire, I say it's beyond silly as a mechanic. It's just dumb, and provides yet another aspect of the worlds they create as being less than believable. That said, knowing Larian, we'd be swimming in alchemist's fire anyway, so it wouldn't be much of a limitation. That may very well be their thoughts on requiring the expenditure of a consumable resource.
