Disagree, this isn't like a sum is greater than the components thing. You can like tuna fish, you can like chocolate ice cream, you can like mustard, that doesn't mean you should mix them all together.
I don't want to see a bunch of amalgamated, mishmashes of everything everyone likes in every single character, that's like how the MCU tries to make heroes and villains now. You can have a bunch of separate, individuals that differ in more ways than just name and race. Nor do you need to like everyone or expect every character to be perfect (for you).
Some people don't want chocolate in their peanut butter. Some people just want peanut butter or chocolate, and having a variety of different character that aren't all potpourri is fine. Diversity and variety means a broad selection, not that every single selection contains everything, because trying to do that will always fall flat and fail.
I am not saying stop complaining (this is Gripes, but if you want it, put it more in Content I'd Like to See), just consider this my Gripe about hearing how every character put forward as a solution is immediately dismissed because they aren't every single perfect thing or because the writer didn't want to make the character that way.
