Add one thing, take one thing.

Add: the ability to straight up murder people mid-convo again.

Remove: Anything that requires jumping. What the fuck, BioWare.

Remove: "lol to be continued" endings that leave you wondering if your protagonist's story is truly over
Add: endings that give the story and protagonist some satisfying (or terrifying) closure

Remove: Mage / Templar Conflict

Add: Extensive deep road reclamation.

Add: Divergent storytelling
Remove: Live service elements

There's also the magic swords you can get in Trespasser that just have it as the hilt until you use it and a magical blade appears. 

This! A thousand times, this. Isabela having a whole pirate themed tree, Merrill and her very specific blood mage + Keeper stuff, Justice being intertwined with Anders' abilities... all of that is so much more unique and interesting than..... Cassandra being a Templar even though she's actually a Seeker and Seeker abilities are explicitly different from Templar abilities.

Remove: Mounts, honestly. I know a lot of love went into them, but they stop party banter from triggering and you can fast travel pretty much everywhere, so it's a feature I can live without.
Add: More diverse weapons! Like flails. And spears. We haven't seen spears since DA2. Actual daggers that aren't short swords! Axes that you can dual wield!

Hahaha, were mounts even faster than walking anyway? Didn't seem like it.

Add: Capes as separate equippable items, similar to Greedfall.

Remove: hats. Sorry bioware, but you prove over and over again that you cannot do hats.

Remove: Rectons
Add: Original source material

It's better to evolve a story naturally than go: er yeah, that's not the case anymore, or, it was really always like that, we've...only just found it.

Retcons are far too obvious & a bad storytelling idea...plus one of the few things that genuinely offend me (think that's the writer in me).

My thoughts.

Add: great hairstyles(somewhat subjective I know)
Remove: dwarves

*hides in a hole to escape the wrath of dwarf fans*

Add: better weapon designs (cause the two handed weapons kinda looked dumb on a dwarf and an elf).

Remove: Fetch quests.

That reminds me:

REMOVE: Having any character tell me how other people are feeling but particularly how I am feeling. That whole exchange between Cole and Solas about the Inquisitor after he broke up with them was irritating to say the least. Please don't force emotions and thoughts on me that I may not have. However, it also threw me having Cole talk about Dorian's memories of a former lover instead of Dorian being able to tell me about it himself; it didn't feel good to know second hand about his thoughts on that guy when he was in a relationship with me. To be honest a lot of what Cole said about other people's personal thoughts was just creepy, cringe making and made me feel bad for them. In fact, if he was so good at picking up on people's emotions, then he should have been aware that people don't like you doing this. Most of what we learnt about our companions inner thoughts did not come from them direct but via Cole, which means we were often party to their thoughts even if they hated our guts and would never normally reveal them to us. No, no, no!!!

ADD/RESTORE: My companions telling me how they feel because we have built up a relationship of intimacy and trust, whether romantic or just good friends. For example, Zevran telling me about his former lover and why he really took the job against the Warden. That was meaningful and would have been totally ruined if a third party had just blurted it out.

And this is meant to be compassionate because....? Fair enough if he talks with them in private and then suggests they tell the other person. It was also clear that in certain cases the writer seemed to think that making some of the more cringe worthy revelations about things people had done in private was meant to be humorous. Cole blurting things out being unsettling was one of the few things I agreed with Sera over and yet I was never given the option to tell him to stop doing it.

In the end I decided on balance that I'd rather make him more human as this would put a stop to that sort of thing. If you keep him a spirit he just becomes even more creepy.

Note: I also don't recall him doing that sort of thing in Asunder.   I much preferred that version of him.
