Coming in here to say that Dorian is *really* winning me over.
I pretty much went in neutral on everyone, except for being incredibly curious about Solas and already being a Varric fan from DA2. Rolled a female Lavellan that I'm still working through my first playthrough with (I'm thoroughly spoiled about All The Major Things, though) and she's romancing Solas. But man. I just got Dorian's personal quest last night regarding the letter Mother Giselle passes along as well as the Mother confronting him later being suspicious because he's a Tevinter. Between his father's quest and then having to defend him against the Mother afterwards... just everything about Dorian's responses was amazing. Pure amazing. I ended up getting a friends-to-the-end sort of speech from him afterwards that just absolutely warmed my heart. We're besties! 
He's quickly become one of my favorite companions, hands down. Enough so that I've actually kicked Varric off my go-to team and am dragging Dorian around everywhere with me (alongside Solas and Iron Bull).
I was really torn on what to do with my impending second playthrough... I've Inquisitors in mind for Cullen, Bull, and Dorian... but the way Dorian's friendship arc has gone, that pretty much made up my mind that I'm gonna roll a male Lavellan for him next playthrough. I may not even wait until I'm done with this first one... I may just go ahead and roll him and do tandem playthroughs. 
David Gaider did a fabulous job here. Really, really love Dorian.
(And since it seems to be a current topic of conversation, I'll admit to being a hetero female gamer.)
