What gives you that impression?
Troi never, ever, struck me as being treated a sexual person, at least from the audience perspective. From an in character perspective, it is difficult to judge because she really is not show in relationships that are not dysfunctional or broken up in some way. Her and Riker are estranged at first, and then she has the marriage with Wyatt in Haven. Then she becomes essentially the emotional abuse victim in another episode. And then there is the on again, off again thing with Worf.
In any case, regardless of what the characters were meant to be, T'Pol and 7 of 9 were certainly designed to appeal to the sexual attractions of the audience.
Your completely missing the point.
Your right to say troi was never suppose to be an obvious sex kitten, but that is exactly the point I was making.
Imagine the three were real people.
Troi was a very social person who pursued pleasurable experiences. She loves chocolate, she related to many people on emotional levels. She came from an upbringing where being naked was normal. She was a counselor it made perfect sense that in her role she would just to wear more expressive clothing.
Seven and tpol, were emotionally unavailable and would never of wore a catsuit if they understood the realities of wearing that type of clothing.
This completely ignoring the fundamentals of such characters is what made the decisions so incredibly stupid and a total low point for the show.
