I'm not wanting kisses or animations or faces made during kisses, I just want one more line of dialogue for Wyll, so that he can decide his own fate, same as everyone else. I don't think, that is over the top or too much.
It's not too much.
Wyll is the companion I wanted to have by the side of my goodish character. I found it very dissapointing to learn that he was not at the same level as Astarion in terms of story and development, but then again I have not seen everything for my self. I heard his new romantic greeting still does not trigger properly on DUrge. I'm glad he got some attention in the latest patch though.
I think he is underrated because he is underdeveloped, and like you say a little too dependent on Tavs decisions which hurts his personality.
