Truth is I was hoping initially for a romance with any of Gaiders characters, because of Zevran and Fenris, but when I knew there was no chance for a female PC with either Dorian or Cassandra, I started begginf for Solas to be an option, because he was the only one that seemed interesting... And I have to say that thank the creators, the maker and everyone else, because I couldn't be any less interested in Blackwall and I've tried Iron Bull's romance and I have to quit, not because of the sex part, which I'm fine with, but because of all the "I know what you need", "Let's lay some groundrules", "let her rest"
so not for me... I don't think I could emphasize it enough
As for Cullen, it would be going back to ME and romancing Kaidan: he's very good looking, he's very sweet and I find him very not atractive. I've done his romance (at least this one I could end it) but meh... It's the kind of romance I'd make canon if there were n better options only because I always have to romance someone 
btw, on the subject of hot elfs, I always thought my thing was Gaider writing, not elfs, but now I don't know... I did prefer Legolas to Aragorn 
Also, about Solas/Shartan, I'm with the skeptics. Maybe he's the "maker", the one who talked to Andraste in her dreams, but more than that I don't think so. I'm totally on board though with elven gods=old gods (I think that could be what made him so angry about the wardens trying to kill them)
