I was hoping for combat improvements in patch 4. Once you know the story, you can still replay the game for the combat and to try out different classes and character builds. But the tactical combat still suffers from many issues.

Backstab is too easy and powerful. It could be turned into Flanking that gives +2AB and requires two attackers. So it wouldn't be the default attack mode that gives free advantage.

High Ground / Low Ground should similarily be a +2 / -2 swing at most. Even at +2/-2 it would still be a 4 point swing that would single handedly win fights. The real "advantage" of high ground should be that you can move back to break line of sight with those below after you attack rather than a flat attack bonus or penalty.

I was also hoping for a more robust Long Rest / Short Rest system that would be more meaningful and integrate the eating food part of the game.

And since we are not getting more story in EA, I would very much like new clothing / armor / weapon models, and class building options for replayability. Starting equipment to customize your character properly.

Level 5 would be nice too, since that's where the classes are starting to come into their own.
