I wish they had used her better in the game. When she was killed off in the T2T, it felt more like they were trying to get her out of the picture to end the Farah vs. Kaileena debate. The writers of the original game were reportedly not all that pleased with the direction that WW took the story and wanted to eliminate as many ties to WW as possible. I didn't like that, after being a central character of the second game, she was basically a non-factor of the 3rd game.
I agree that WW was WAY over sexualized. Kaileena was an immensely powerful woman who controlled the Sands of Time and was in control of her own kingdom...because when women are in charge, they choose to parade around nearly naked in high heeled knee boots or metal thongs . They could have gone for more reasonable (and time-appropriate) clothing while keeping the sex appeal, but they choose to make Kaileena and Shahdee look like girls off the cover of a cheap romance novel or porn DVD simply to get the attention of the hormonal 15 year old boys...completely unneeded.
All in all though, she was a great character, and very deep, especially for a video game. I wish they had utilized her more...and better.
