The gear design team and the raid design team are not the same. Cutting back on glamour would just mean that those in the gear design team would have less to do and more time to do it. And that money that isn't being spent on glamour cannot magically make people who are qualified to design fights appear. Yoshi-P has explained this before when he talks about not lacking money, but Square Enix lacking people who are qualified enough to design hard fights.
I would rather have a few well-designed fights than a cesspool of mediocre to bad fights, personally.
