RobNJ said:Completely. Who says because they are published their use is compulsory? Lots of books also come out with new magic items and weapon types. That doesn't mean I allow a profusion of weapons and weird magic items in my game.
It really depends on the DM and the group he plays with, and is out of the hands of WotC, really. I think the problem is a lot of DMs get "suckered", and I use that term loosely, into using PrCs they don't necessarily want to because quite often it's the players who are buying the splatbooks and asking to have material incorporated. Nothing WotC can do about this, per se, though they end up getting blamed for putting out the material to begin with.
