The Wonder Rogues are fine villains, they just don't get as much use as others. For various reasons, not the least of which being the perception that Wondy is 100% defined by Greek myth, and most of her villains are some manner of scientist or technology based.
Though really, the main issue plaguing them is the lack of exposure in other media. Nobody outside a few nerds gives a shit about comic books, so most people know of these characters from adaptations. There are very very few adaptations of Wonder Woman, so her villains simply haven't got any real exposure until now.
