I won't really add much to what people here said, but I really want to add my thoughts into the matter, if CDPR decides to make an enhanced edition or something similar to the sort I really hope they do the following:
1-
More development to the Wild Hunt, especially Eredin: (pretty much copy pasted from the Wild Hunt portrayal thread, hehe)
Having Eredin Breac Glass only have 5 lines in the entire game is a huge wasted potential, this is not some normal character, this is the nemesis of both Ciri and Geralt, let us see him torment Geralt with visions like in the Witcher 1 (where he was represented perfectly) throughout Witcher 3 like after an act finishes or implementing a Ciri flashback from the time she was in their world and let us see the real side of him like we did in the books, or better yet, add more lines to him in the scenes that we see him in, Caranthir and Imlerith had satisfactory amount of development into them, but Eredin needed a lot more, also a scene of him without his damn helmet.
2-
Let Ciri comment on Geralt's love choices:
It is weird to see Ciri not giving a flying fuck when Geralt basically chooses Triss over Yennefer or if Geralt chooses to be alone and Ciri not commenting on it.
The appeal of the Witcher series is that you are immersed in the mindset of a fully developed 3-dimensional character and that includes his love for his child.
But this is the Witcher, there should be no one sided-views for any character, all the villains in the series had intentions you understood so you felt bad about killing them, however, the Wild Hunt's intentions (meaning Eredin) were not explored enough, I personally know his intentions and what he really is because I read the books and if it was explored in the game it would have added way more to the already awesome game that is the Witcher 3.
But I agree, like you said, you should really hate Eredin because he is threatening your daughter and would outright kill her to reach his goals but also having a feeling of understanding his intentions on the back of your mind, that would have been perfect.
