In the end there isn't really much to say about this.
The question is just: Is Larian even just PRETENDING to make an effort into making their visual representation have some degree of verisimilitude OR they genuinely couldn't give less of a damn and the wacky/zany/cartoony vibe is exactly what they are chasing after?
Given the mixed vibes so far, I'm not even sure they have decided this themselves, yet.
Also, aside for the impromptu "Lul, shit is funny" is anyone ACTUALLY willing to argue that the current implementation adds something to the game, while more "grounded" physics for falling bodies would impoverish the game somehow?
Well the foundation of the move is already silly - I mean I was sort of joking with my post but also highlighting that the only feasibly way to shove someone AFTER you attack them is: if after you swing you leap crotch-first right into their face which would explain the bizarre trajectory of the "shove". The point that has been made a 1000 times is "if you could just shove someone why would you not just attack again?"
And so if we are going to be silly I say stick with it. In Multiplayer its a great source of humor. I know that's not your thing, but really anything that makes combat more over-the-top is a boon to multiplayer.
