The issue is that these things aren't base part of dnd rules, they'd be things you would ask your dm to do using some stat or specific situation. And most of the time these things could fail like the aforementioned rogue flipping. But BG3 doesn't give any of these a fail, they are all autosuccesses with big advantages that shove the other rules out, which DnD combat was constructed around those rules. OAs are very important, and being able to disengage for a bonus action is super rare. But these changes, the cheese, makes it common and easy to ignore 5es core and play the game too similar to DoS.
