Good to know that
.
However, as much as I like Sera, my arguments were directed at the heterosexual romance. My male Inquisitor cannot romance Sera you see. He is stuck between a Disney Princess who friendzones him and a more-sword-than-sense, over-the top religious woman with a poor taste in literature. Hence my complaint.
I will however, agree that Dorian's romance and Sera's romance were done well. Sera's especially.
If you think Cassandra is "over the top religious" then you kinda failed at making her change her views on you (which i guess its only avaiable for the ones that want to romance her).
I personally loved the way you can make her more understanding of your anti-chantry position, plus i dont find it one sided as with Josephine, Cassandra surely doesnt belive that you like her at first, but she likes you and definitly shows that during the cutscenes, either by holding hands and acting slightly out of her normal personality or just outright telling you during her "The Ideal Romance" quest.
Its also cool that you dont need to pick the "woo" option every time to romance Cassy, she values someone who has his head straight, so no need to be a romantic dofus when in a situation that doesnt requires it.
Of course, when the time requires for romantic goofness, then Cass is all for it 
I guess we just have diferent opinions, while i really liked Dorian's character (even tho the "Gay son/Father disapproves" is such a cliche) i will have to disagree on Sera, i really found her to be a poorly written obnoxious character.
So much so that i think the developers knew that and thankfully allowed me to boot her out of the Inquisition at any time.
