That said, because I know I'll hear this argument, not all harpies have to be Intelligence 7. Maybe there're smarter harpies somewhere who think, "Hey. We have wings. Let's fly and throw rocks instead of getting up close and attacking people with our clubs and claws."
Whatever. The point is that SO many creatures in BG3 seem to be special like that. None act the way their race is designed...
This is an interesting point. Like the rules of mathematics, a game has a set of rules that players rely on to come up with plans of execution.
D&D has its established rules, definitions, history, etc. I'm imagining a situation where an author publishes a math book where the addition symbol (+) were replaced by @ and the division symbol (/) replaced by #. People new to mathematics would learn the new symbols and not know the difference but for those of us who have been using math for many years it would seem *almost* insulting. Even worse if the "+" and "/" symbols were redefined to perform some other operations.
So, perhaps if just one harpy in the group acted exceptionally, and was illustrated in a way that distinctly identified that harpy as "the odd one", maybe that could be worked in...no? I think an exceptional harpy would be better off featured as a boss fight, though.
As I type this I realize that this is the "football" argument GM4Him made some time ago. Not that this is necessarily a bad thing...people forget without reminders...
