Just because I don't use barrels, grenades, shove & jump it doesn't change neither what the AI is doing nor how the encounters have been balanced. Just watch Swen play during the panel and you see that they designed the encounters with these options to be used in mind. The encounters are especially balanced and designed to be using the stealth + enemies stuck in turn-based-combo.
Animals climbing ladders... I don't mind bears, but cows probably shouldn't even if its mainly just to keep the party movement less annoying (as Larian dropped the ball on controls to beginn with). For me the other changes to the Druid class are far worse and not to mention that publicity stunt to do the animals' animation for the show before fixing the animations of creatures using the small humanoid rig - as Niara mentioned.
...but its all about Swen's perception of fun, so seeing how closely BG3 encounter-design resembles DOS2, I don't exect anything to change.
