Yea, by far too...unless she plays a huge role in the story which wouldn't be surprising. It'll be interesting to see Bioware's reason for her not being an LI. Varric - Bianca, Leliana - Warden, Cole - Has the mind of a kid you sicko. Vivienne - ?
Her playing a huge role in DAI's story may just be the reason she's not an LI. Of course the two don't have to be mutually exclusive, look at Morrigan. Just saying maybe it's somehow the case this time.
They said there's at least one character you can't get rid of...I had assumed it was Cassandra but here's hoping it's Viv. If she's too story important then that would be great.
Plus maybe she's already romantically entangled with another important character and it's an adorable ship and people will love it.
Or she'll be like Aveline and we all just wish we could romance her so much, but don't hold it against her that we can't.
I know she's going to be a near permanent fixture in my parties.
