Though story, characters, choices, and roleplaying ability(storywise, not assigning points or whatever) are my main concerns, there are some things I would like changed about the combat/gameplay. The style of combat in DA has NEVER been something I enjoy so I don't expect to love it no matter what direction it takes but there are improvements that would make it more tolerable in my eyes:
-Give us back the ability to set detailed custom companion tactics. I shouldn't have to manually micromanage each little task in every battle.
-Get rid of any requirements system such as the "war assets" from ME3 or the "power" system from DA:I. If you want players to do side content, make the side content interesting. Don't give them the worst possible ending unless they grind multiplayer that they are not interested in or outright force them to do repetitive and menial tasks to advance the plot.
-Bring back "zoomed in" conversations. I don't need anything cinematic, simple shot/reverse shot is fine but let me see who I'm talking to!
-Make sure the companion AI actually works and does what you tell it. If I manually move Varric away from a dragon (out of dragon melee range) but still within range of his crossbow, he should NOT immediately run back up to the dragon's face and then start shooting it.
-More and greater variety in combat abilities. Upgrades to the same few abilities are all fine and dandy but it felt like that was the majority of what was present in the combat skill trees.
-NO limit to the number of abilities you can use during combat. That 8 ability limit was crap. Even on consoles you could use the radial menu to use any and all learned abilities or carried items in DA:O and DA2. There was no reason for this and it made zero sense.
-Better unique rewards and a greater variety of armor and weapons both in looks and in special enhancements.
