You can be patient and optimistic and willing to wait for an another opportunity to create real change.
I have been patient and optimistic. It's been three ****** games and nothing has gotten better. The few times it seems like things are getting marginally better, they're back to where they started within a few years.
Besides, while Solas and his tomfoolery may be detrimental to Briala's efforts, the fact remains that if you picked her as ruler of Orlais she's been made marquise of the Dales and has taken down alienage walls throughout Orlais.
By the end of Trespasser those alienages have not been said to be rebuilt on account of Solas, so until we learn otherwise the the elves of Orlais have greater freedom because of YOUR noble actions.
Until humans take it back the way they took back the Dales from the elves, then took back the better treatment they promised the Denerim Alienage for a City Elf Bann, or they took back the Hinterlands they promised to a Dalish Warden.
Also, what happened for an Inquisitor who sided with mages and elected someone besides Vivienne as Divine? Didn't mages also get to enjoy "greater freedom"? How long did that last? Two years, until Vivienne restored the Circles.
Like I said, no meaningful, lasting change.
Don't bother getting your hopes up, because it's not going to last.
Without conflict, there is no interesting story. If they resolve everything, then the series ends.
I'm not saying all conflict should be magically resolved and everything should be all hunky-dory, but by the same token, when they constantly rub our faces in how much life sucks for everyone but non-magic humans then give us a chance to try to help them, I'd like things to actually get better and actually stay better for longer than just a few years at most.
It's never new conflicts with new challenges for these games (like "mages are no longer locked in towers; now we need to figure out how to integrate them into non-magic society" or "elves have increased legal rights, and humans don't like this; we have to figure out how to get these two to coexist"), it's the same old conflict with the same old song and dance because the writers keep finding new ways to completely undo any progress the player character makes for a group and just restore the previous game's status quo.
It's the exact same conflict game after game after game ("Templars lock mages in Circles" "humans herd elves into alienages or out of human settlements", etc), and after a while you get tired of taking the exact same stance in the exact same conflict the fourth game in a row, since you already know nothing you do is going to make a meaningful impact, and any new development will be undone by the next game, so why bother caring?
If a hobby is bothering you like this then ...maybe you should find another? Just a thought.
That's what I'm seriously considering. Learn to read.
Oh? How is your life even remotely close to a casteless dwarf or a circle mage's?
You know nothing of real oppression.
You have no idea what my real life has been like.
Don't go making assumptions.
Depends how meaningful you need the change to be. I found meaning helping Zerlinda and her son, comforting Athras when his wife died horribly and painfully as a werewolf, taking off Vaughan's head for hurting Shianni, making sure Merrill and Fenris and Sera had some sort of safe haven and support system, freeing Zevran from the Crows, saving the lives of mages three games in a row, giving Briala more political clout through Celene or Gaspard, protecting the casteless from Harrowmont's... everything, etc.
You don't have to enact big, sweeping change to make a difference in someone's life.
And then the second you take out these individual oppressors, new ones will just fill in to take their place.
It's like stomping on an anthill; you might take out a few individual ants, but there's a whole system colony underneath with a queen ant breeding a hundred new ones to replace the old ones. The system of Thedas' socioeconomic hierarchy breeds this level of injustice, so just taking out one or two here or there doesn't make a meaningful, lasting change.
