I completely agree. Would love to have a little more of a romantic scene as an ending, even if it wasn't a perfectly happy ending.
Also a very minor complaint but as a dark urge
more reactivity to the death if you reject bhaal? It was really odd that through the game he reacted negatively to the player getting close to death or dying but when it happened there wasn't really a peep out of any companions and it felt like this wasn't really brought up ever again. Super weird. Very nitpicky complaint.
