I'm pretty certain I'm not the only one who noticed, but the new lore and information put the Dalish in a new perspective, and not a very good one.
First, the whole thing about them not really knowing their past at all. That's excusable to a degree, they're holding on to whatever scraps they think is Elven culture, even former slave tatoos. But the sheer ignorance is rather unfortunate for a group that seems to pride itself on being the last remnant of True Elven Culture and had a huge chip on their shoulders because of it. It seems even Morrigan knows more of elves than the Dalish.
Being proud of being free of Andrastian humans who want them to convert and live in perpetual servitude is hardly a bad thing. We also have the rather problematic issue of the quest sometimes confusing the Dalish Inquisitor for a human Inquisitor, such as the line where the elven protagonist asks Morrigan who Mythal is, which is akin to Leliana asking Morrigan who Andraste is.
Still, not as bad as the wonderful custom of dumping excess mages out the camp at seven and letting them fend for themselves. No friggin wonder Minaeve is pissed off at them and wants nothing to do with hr own culture. The Circles still seem preferable than being thrown into the wide world with no family, no clan, no protection, and no anti-demon training. Maybe not all clans practice this custom, true, but it's still an awful thing to do to a child.
You're referencing a single clan, and the dialogue with Lavellan can have him say that Clan Lavellan would never do that, since they allow mages to stay with the clan, and allow them to go with clans who need mages, like Clan Alerion did with Merrill. Merrill's codex also reads that this is actually a very common practice among the Dalish: "As each generation passes, magic becomes more rare among the Dalish. As the gift dies out, talented children are moved between clans so that every Keeper has a successor, and no clan is in danger of being left without guidance."
There's also the example of Zathrian's clan, who welcomed another mage into their clan when they already had three mages, and never exiled him or brought him to another clan.
Then, we learn from the Dalish on Solas's first personal quest (where you activate the Elven artifact) that her Keeper summoned a demon that wiped out the entre clan. How many Keepers or First did we see use dangerous magic to the detriment of their clan now? Zathrian, Merill, and now this. These folks don't seem to have much discipline with their magic.
You're judging an entire ethnic group of men, women, and children who live across the entire scope of the continent (and who have thrived for centuries after the fall and occupation of their homeland) based on three people? That's quite silly.
And then, the final nail in the coffin comes in the Knights's Tomb: for some time it was (mostly) accepted that Red Crossing was an excuse by the Chantry to wipe out the Dales. Turns out, the Dalish did attack the town, for no other reason than one of their own decided not to follow their creed (so much for freedom eh?). So while the Exalted March might have been overkill, coupled with the fact that the Dalish refused to help during the Second Bligth it's still hard to feel sorry for them.
You mean the story in the scroll started with the murder of an elf by humans, and Emerald Knights were tracking one of their own who they were worried might spill their secrets. You're also leaving out that the scroll references previous fights with humans at the border, and that even the quest itself involves Keeper Hawen's clan admitting they were wrong because humans and elves were responsible for the start of the war.
We're also not factoring Emperor Drakon's issues with the Dales that prevented him from conquering the Free Marches, the border skirmishes between the two nations, the Andrastian incursions into the Dales (by missionaries and templars) to force religious conversation that are referenced in the historical accounts of the City Elves and the Dalish. It's hardly one-sided.
