I agree with Olórin and I'd extend the sensibly part to almost all classes. The weapon master PRC is also built as a japanese samurai in mind, but as Olórin said, it all depends of the players how they play their characters. Are the feats names and descriptions taken too seriously? They just represent the skills the characters have learned. The different ways to learn a same skill are many... Ki strike, perfect body, diamond soul, etc. Should aura of courage automaticly mean that all paladins are completely immune to fear? Common sense and imagination are the tools that help in here. But it would be nice to have few different kind of prestige classes for a monk-type character. The more options there are more easier different people find what they are looking for.
