Unpopular opinion: Straight Male romance was shafted.

A romance with either character didn't really make much sense to me (obviously that's just my personal view for my specific protagonist and not a general statement). My protagonist, Revas, helped Cassandra locate the Book of Seekers, and assisted Josephine with her family dilemma, but I just think the differences are too irreconcilable because they're both Andrastians and see things a particular way. Cassandra asks if there's room for the Maker in your religion is somewhat similar to a Christian asking someone who is Jewish if there's room for Jesus in their religion (it's an incredibly problematic thing to say to anyone), and that doesn't touch on her comments in the Temple of Mythal; Josephine seems to brush aside the cultural and religious dynamics of the schism between the Dalish and Andrastian humans during your conversation that comes across like she doesn't really care about the People.

To clarify, I don't think either character is bad; however, I think there's a cultural and religious gap (with both women looking at the world through an Andrastian lens) that's never bridged with the Dalish protagonist throughout the entire story, and that can be a problem for some Dalish main characters. In fact, Harding is the only one who even comments on you being in the Dales when you say the Dalish mantra.
