Pretty much all of these are valid criticisms, most of which carries over into the current patch still.
As you mentioned, group jumping has been added - but it's a bit finicky still, and it doesn't resolve the many other issues you note.
Pathfinding has been improved somewhat in the latest patch - characters should walk into fire and brambles far less now - but again, it's not perfect yet and it's still fiddly at times to move characters through dangerous areas even when the threats are well identified.
I'd add to what you say on movement - the current ungridded movement design actually makes in-combat movement a real chore, where you are expressly wrestling with the controls and the UI to do what you want. Asking a character to move around behind an enemy becomes a game of hot and cold with the mouse to get them to pick a path that will put them where you wan,t and also not provoke opportunity attacks... or it becomes a game of cautious tiny two foot steps as you edge your way around manually. It's not well implemented.
Adding my second to drawing attention to all of these critiques.
