Good points you have there.
I also bounded Q and E to the pivot camera, helped a little but the whole camera management can use some tweaks for sure.
Fighter - I still feel they can use some extra actions (Available from the get go) - i wish if they would be able grab somebody (though i heard if you are strong enough you are able to throw bodies?) or able to taunt (maybe these will be availble only higher levels?). Also if piercing/slashing/bludegoning damage could be explained how they react with enemies armor and hp that would spice it up a little for melee chars.
Jumping +disengage mix and the current action economy (you can swap weapons, dig in the inventory for no cost) is just wierd. I understand what they wanted to achieve here, but as many others already said, its only fun to shove and jump during combat the first 3-4 times. But it gets really repetitive, tedious and strange once you are over some battles, also it slows down the combat (also yeah jumping distance atm really breaks immersion). I think an implementation of some kind of flanking/positioning rule would be nice. Dodge could be an action for characters who would just stand there otherwise. Diverse enemy AI would also help (different behaviours as per monsters' intelligence so you need to accomodate to their tactics and vulnerabilities)
For dialogue checks, these will be easier once they explain more how you can improve your chances (potions, spells, scrolls) and once they implement that other party members can assist to checks(if i remember well they said in an interview they are working on this) but it would be nice if you could also increase your chances more as you can in Disco Elysium, with doing things/exploring (e.g.: you found a letter so you have a better chance to convince this guy, you spoke to her friend so you know what to say etc.) and that is rewardingly visible on the UI (encouraging you to do more if you feel you have low chances).
It can be a huge game for me, the foundation is there. but atm combat did not convince me and there are tweaks needed for other stuff as well. but this is EA and hopefully Larian listens and at least give us toggles for all stuff people are complaining about.
