Caught that, did you? Lol. It's kind of a shame Blackwall was meant to be the default romance for a female I quisitor. The one with Solas seems so much more natural. And if I'm going to be lied to and left regardless, I'd rather it be by Solas. Even if Blackwall does come back eventually...
I'm sure Solas will return eventually as well. And it will be magical. #teamoptimismftw
I don't normally, but given how colorful this thread is... 
On the "romance enhances the story" topic.
I was originally going to romance Cullen. That lasted... well, five minutes into the game, up until I met Solas. The scene where you meet him for the first time - just the my Lav looked at him after he introduced himself screamed "there's some chemistry going on here!" to me.
Then there's his talk about the orb. I think it feels much more powerful if you romance him; like he's trusting Lav with information he wouldn't give to anyone else, which feels like a confirmation of trust between them.
Then, his narration as he leads you to Skyhold. I don't really see him and Lav as equals here; it's more like he becomes a mentor figure, and I love it, because it goes to show that he really is more than he pretends to be. I love the way he guides her, but doesn't want recognition - or anything else - in return and lets her look like a hero to others. I really wish there'd be an option to thank him for that. Then, when you reach Skyhold, Lav is like "Woah~", and he just stands here, looking pleased. Aww.
...so, this is the reason I could never romance anyone else. All these scenes just scream "chemistry!" and feel so much more powerful if you are romancing Solas

That's a really good point. I didn't notice it too much the first time I played and still thought I might romance Sera, but after playing that scene again knowing my Lavellan and Solas would later fall in love, it just seemed that much more pronounced.
You're right, he definitely comes across as a mentor here. Many people have noticed parallels with Merlin and Nimue, and it's deserved.
I guess when I say "equal," I mean they shared equal weight in leading the people to Skyhold, in building up a great military fortress that restored people's faith and devotion to the Inquisition, and ultimately building the Inquisition into a world power to stand against Corypheus. Again, Solas has the knowledge and understanding of how to get things done, and Lavellan follows his guidance in getting it done. If Solas had been the one to tell the people "I know a safe place we can go," it wouldn't have meant as much to them as if the Inquisitor did it, and they wouldn't have revered you as much as they did, and the Inquisition wouldn't have hit the ground running as it did the moment you entered Skyhold. Likewise, you wouldn't have known what to do or where to go to direct the people's faith as well had Solas not spoken up. You are the figurehead that people follow, but Solas is the power behind the throne that directs you where to lead the people.
And I don't know. From the moment the singing stops, I love how the scenes leading up to the discovery of Skyhold focuses on Solas and Lavellan. Everyone is still glowing with blind faith that the Herald will make things better, but you two are having the practical talk of "This is the way things really are and this is what we need to do to fix it." Then you two do the necessary work and planning to lead the people who have blind faith in the Herald and rebuild the Inquisition into a world power it needs to be to stop Corypheus.
It's just... I can't explain. It just feels so much more meaningful with a Lavellan romancing Solas.
I tried Knight-Enchanter yesterday for the first time. Oh. My. God. It's not just overpowered, it's insane! The only downside is that enemies tend to kick me down on the floor, so it's kill-kill-kill-roll-on-the-floor-kill-kill-kill. Knight-Enchanter kills everyone. Knight-Enchanter got a permanent barrier(sort of). Knight-Enchanter looks cool. Knight-Enchanter never runs out of mana. Knight-Enchanter protects Solas. It's not "hey, me and Solas - two Rift Mages together!", but it's still great.
You know, I wish that Presence from the Arcane Warrior quest in DAO could've seen one of his people doing that combat stance. I think it would have been proud.
Hah! I'm glad you said this.
I'm replaying my female Lavellan from the destruction of Haven onward, and decided to choose the Knight-Enchanter specialization. (Last time I couldn't choose between it and Rift mage, and so didn't choose any specialization at all.) Hopefully this time I can act as party tank/protector and not have to take Cassandra or Blackwall everywhere to fill up a companion spot I'd rather give to Cole.
