I’ve no strong feelings either way, but you two apparently do. Why is that? What’s wrong with eye-catching combat?
Because all those will do, will be looking nice in a trailer, and perhaps for the first 1 hour of gametime. Afterwards it will be a frustrating waste of time. It is not an action game, where animation recovery or visual/audio feedback are part of the gameplay. You will never get this satisfying "wham" effect you get from the good shooter or an action game, because gameplay is making tactical decisions, not fighting or shooting. BG3 combat is boring, because tactical decisionmaking is boring, not because it doesn't mascarade as an action game.
Where I think BG3 could use polish is responsiveness - ability animations not locking out player imput, smoother control when switching between characters, better UI etc. Adding more uninteractive fluff won't do much good in a long run.
