lol Merrill you're making a terrible case for yourself. Ok, I'll take Solas back, thanks for playing.
Yeah I liked Merrill but when I tried talking some sense into her back with the Eluvian business she was really hard to reason with. That would've driven Solas mad. At the very least it would be interesting to see them interact. I know she had some interesting views about the Eluvians but yeah her views about spirits and the Fade?

I've never understood this rationale. Hawke is a human who knows nothing about elven culture, the Dalish, or the Eluvians, while Merrill is someone who painstakingly put the time into studying the lore on the Eluvians and extrapolating information from the shard. Hawke is ignorant about this, while Merrill is informed, but people act like Merrill should simply fall in line to rivalry Hawke.
If anything, TME and Inquisition only proved Merrill right about how beneficial the Eluvians would be for the Elvhen, particularly as it's an asset that Briala used to get her elven network up and running against one of the strongest empires in Thedas. And the Inquisitor has an Eluvian in Skyhold, a gateway to the Crossroads.
As much as I liked having Solas as a friend, I really miss having a pro-Dalish character in Inquisition. It felt too biased in favor of the Andrastian mindset in many places (particularly when so many characters speak negatively about the Dalish, while the only person in the inner circle who can speak positively about them is my character), while we get a plethora of positive dialogue from our advisers, companions, and even minor characters about the Chantry or the Andrastian faith. Cassandra even talks with Lavellan about following the Maker, even when he's explicitly stated he follows his own gods, and she says the same to Solas. I don't really understand why it's so one-sided, which made it quite lonely and frustrating as Inquisitor Lavellan.
Given all the negativity towards the Dalish and the lack of coverage for the elves (particularly in the Dales, which is supposed to be predominantly elven, and yet focuses on human characters over elven characters), it would be nice if Solas heralded some positive coverage for the elves for a change when he returns. I'm a little tired of the Andrastian human bias thus far.
