But where is this "choice" you speak of? There is no choice. No *real* choice. The choice to not use the tadpoles is *not* a real choice.
Whether the player uses or doesn't use the tadpole is a choice which the game reflects on in the very 2nd conversation with the Guardian during ACT 1. I played my first playthrough without using them because I wanted to keep my character a pure Drow and enjoyed it thoroughly, so there's that roleplay choice I spoke of.
So what you consider a "real" or "meaningful" choice is irrelevant. It's a choice which the story reflects on and it's very much real. Is it meaningful? To each their own, it is to me. I enjoy when a story takes actions & choices into account and reacts to them.
