People read different characters for different reasons. Wonder Woman fans aren't just drawn to the character because she has a basis in greek myth and can fight. But that is pretty much where we are with this interpretation.
Wonder Woman has a variety of powers. When people are asking for more action, they don't necessarily mean more fighting.
Can you imagine a Flash comic where hall he didn't use his superspeed?
Or a GL comic where he didn't use his ring?
The difference here is that Diana is a multi-powered superhero, like Superman.
We should see her using her superspeed. Her power of flight. Her magic lasso. Her bracelets. Her ability to commune with animals. Her super strength. To solve problems. Not just incidentally before she pulls out her swords or fists to fix things. That is part of the fun of following a multipowered hero. Seeing how inventively the writer uses the powers. And Azzarello just isn't very inventive with them.
This is not to say that he is a horrible writer. Or that he is writing the characterization badly. But he is totally missing an entire element of writing a superhero. And that element is superheroics.
