For me I think Wonder Woman is given some great single moments (She got to kill Maxwell Lord, which we can debate between good that it happened in her comic vs it being a part of a big crossover event)) but she doesn't get the mass market storylines. Wars of the Gods should be considered a ground breaking Wonder Woman led storyline, and most consider it an "eh" and poorly done.

During the Nineties, Wonder Woman should have had both an Wonder Woman vs Aliens and Wonder Woman vs Predator. Xenomorphs land on Paradise Island. Marvel and Dc did crossovers. Batman/ Dardevil. Batman/ Spiderman. Wonder Woman and ... oh wait that never happened.
Wonder Woman died and no one knew. I was reading Justice League Dark, which she was starring in, and I learned she died in that. I'm not even sure what issue she did die in, looks like Infinite Frontier?
