I hope nobody takes my comments on Sera the wrong way I really hope that she ends up being a character that I can fall madly in love with, my thoughts are based on the little information that we have now. She could end up making me forget all about Cassandra like Leliana did with Morrigan. I'm still hurting on Cassandra so my judgment may be clouded.
This also applies for Josephine and hopefully Vivienne.
I think Sera is cute and she'll probably be the one I romance in my first playthrough if Vivienne isn't an LI, but knowing that it was confirmed that she was killed in the preview makes me think that she's completely optional and not a part of the main plot. If she dies no matter what in the end, or betrays the Inquisitor, I will regretfully have to pass, cause I've had quite enough Tragic Lesbian Romances to last a lifetime, thanks very much. Josephine looks and sounds pleasant and agreeable, but that's not what I look for in a video game romance, especially for a character who isn't a companion, and if there's any hint of a power imbalance in the relationship with the Inquisitor that will be a huge nope for me. And although I find Cullen and Dorian attractive, one I have problems with ideologically, and the other is off limits because I don't play male characters.
So yeah, I'm very amused that this Greedy Bisexual may pass on all eight romances, depending on what I hear and see about them.
