The text that I originally quoted was about speculation of Dorian having lesser romance compared to Cullen and Solas plot-wise. My comment is that Cullen and Solas will probaply have less plot-driven romance than him. It doesn't matter me in the end, I was happy romancing Zevran in DAO although that didn't make me prince or got me god baby.
Hm... good point actually... I always go with different options when handling the Landsmeet and the Dark Ritual, but I guess they are indeed critical to the plot. Maybe this means that Vivienne, Cole, Varric, and Leliana will be the most integral plot-wise in DA:I? It could explain why none of them are LIs... although there are many other reasons to explain Cole and Leliana as well.
