CDPR has not let me down in character design yet, and I don't think they're going to get lazy when it'll come to one of the main characters for the story finale.
That said, I don't think the designers should be constrained by character descriptions from the books- they are within their right to exercise their own creativity in imagining book characters, and there's nothing wrong with it if they do that.
Personally, I wish Yennefer would be as close to her book descriptions as possible because I think her book descriptions are wonderful; can we get some scratch and sniff cards with TW3 />
