I agree, I've seen this in 3e in a way that I've never seen in any other RPG, and it is one of the major downsides. Never before has it been necessary (or even desirable) to plan out the entire progression of the character, but in 3e there is almost no avoiding it.
That's a fallacy. The planning out of a character is necessary for those
who already know what their character will be. Hmm. If you have a character you want to be a Shadowdancer, then you have begun with a character concept. You then continue training with that goal in mind. If someone wants to be a doctor when they're at school, they are restricted in their choice of subjects from then on, aren't they?
Conversely, a player with no plan for his character can stumble into a prestige class at a later time, because (in theory) that prestige class will be rewarding the choices he has made along the way.
So, if you had a character who was fighting with two weapons, and had been specialising in such a style, all of a sudden you'd find yourself qualified for the Tempest PrC.
If Prestige Classes were so powerful as to dwarf any other class, then there would be a definite problem, but - in my experience - this is not the case. They're not required.
This ability to plan ahead is a feature of 3e. It is a feature of any system that allows meaningful choice of character development
later in their careers.
It could probably be said that some Prestige Classes are too stringent in their requirements for entry, but that's another subject entirely.
Cheers!
