Then at the last minute, WB wanted longer fight scene and made her change the ending, hence why the CGI and even Ares dialogue become bad. She never says what the original ending was and I can't find any artwork on it, but someone mentioned it was more character focused so it could have been closer to the Gods and Mortals ending where Diana uses the lasso but, ¯\_(ツ)_/¯ can't find anything.
I remember with Black Panther the VFX only had 3 weeks to do the entire final fight scene between T'challa and Killmonger. I don't remember if that's because they were just tight on time or if they wanted to redo the fight.
