If they had given Wyll just a few more lines with Tav it could have been magic. Wyll is the only one who gives me that happily-ever-after fairytale vibe. So, I was kinda surprised how fast it cooled down.
Part of the problem I had with it is that whenever you talk to him he mentioned his father. And I know that's part of his story arc. But I found myself thinking: "If you say 'my father' one more time I'm going to slap you." And yes, he also does this when you don't romance him. But when you do romance him, it feels like Tav is only an afterthought. A couple of romantic interactions with Tav, where he doesn't mention his father, could have prevented this.

And don't even get me started on Duke Ravengard. He's a 'tell, don't show character'. We are constantly told that he's so important but
once you rescue him he's nothing but camp furniture
