It could be a difference of continually being told the Dalish are wrong about one aspect or another of their culture in Inquisition, the recton with the mages in the clans, in addition to having two companions who are anti-Dalish (with no pro-Dalish companions), while being surrounded by characters who are pro-Chantry and talk about how important the Chantry and the Andrastian faith is. It's just another piece of the story where we're told that the Dalish aren't right.
The thing is the Andrastian faith is bigger than the elven faith.
Currently you can't raise army in the name of Mythal to defeat something like the Breach, it's just not happening.
But Mythal had a more direct role in saving or bringing solution to our heroes.
She saved the wardens , who went on to end the Blight.
She saved Hawke who went on to err...cause chaos everywhere.
And in the end it's Mythal who grants you a boon to defeat Corypheus.(also The Dread Wolf save the Inquisitor from dying from the Anchor.The Inquisitor basically walk out of the fade dying )
Anyway yeah the elven faith takes a few kicks in the head , most of their gods had a really darker side , and the Dalish have almost build a new faith at this point.
Anyway it's no big deal , I mean in DAI you can easily dismiss the Maker if that's your fancy.
I mean : The Inquisitor interrupted a ritual , touched an orb belonging to an elven god , got some power from it.
Then he was saved by the Divine , a mortal woman.
Then he was saved a second time by this Elven God who was there because he was looking for his orb.
He raised an army because people assumed it was all the Maker work .
In the fade again you're saved by a spirit .
Corypheus doesn't even know who the hell is the Maker , I mean...?
He's one of the few people who is supposed to have heard His voice , (with the other magisters and Andraste).
Also we got nothing about Andraste ashes ...they just went poof.
To be honest I thought the whole Maker /Chantry stuff was all about faith , you get nothing but your belief there's some higher thing looking out for you/the world.
I thought the elven Gods were more interesting , they were flawed,.They made mistakes , they have revenge fantasies .They failed the elves ...
Anyway meeting Flemythal in the fade was a bigger thing than Andraste who turns out to be the Divine who turns out to (probably) be a spirit(who likes all spirit has no freaking clue about anything).
Also the epilogue.I mean ...I played Dalish , and I think it was a big reason I enjoyed the game so much.
I thought it had some heartbreaking moment when your pc faith (if you believe in the elven Gods) is shaken to the core.
