It seems that creating adventures and NPC villains is time-consuming enough for a DM that adding a prestige class to the design of an NPC is pretty much a waste of time that could otherwise be spent writing a good plot. Personally, I just use a normal character class and if I'm even considering a prestige class, I'll just skip the details and slap on some abilities as feats. Worrying about pre-requisites? C'mon. What DM gives a crap about inane details like that?[/b]
Raises hand.
I use prestige classes WAY more than the players do.
IME, prestige classes aren't that difficult. In fact, I usually have an easier time than the PCs, because I build the end product while sometimes players lack the foresight to pick the right skills and feats ahead of time. Knowing the skill and feat prerequisites, it's a straightforward process of determining what it takes to make it there. If a class requires knowledge (arcana) 8 ranks, I know it will take 5 levels in a class with Knowledge (arcana) as a class skill.
Further, sometimes designing prestige classes is easier than core classes which often have a lot of choice. Fighters, Arcane spellcasters and core classes from d20 modern involve a lot of choices; more often, prestige classes have their abilities defined for them so there is little debate involved. If I know a character is a 3rd level mirror master or gem mage, I just jot down their abilities for a 3rd level character of that class, and I am set.
I'm not particularly fond of the notion "if the DM says he has it, he has it." Prestige classes are part of a set of rules that define the reality and background of the world. If a player is part of the bloodguard, it is nonsensible to have his abilities significantly vary from other bloodguard, for example. In most game worlds, there is no sensible attribute that makes it so PCs would operate differently from NPCs, so doing so in actually would really no jive well with my sense of consistency, and could impair the beleivability of the game.
