3) I'm reminded of a player I had several years ago who wanted to play a iajutsu master. And not just a realistic one, an anime styled one who draws his weapon, cuts once, and returns it once per round. There weren't any rules for one at the time, so I suggested we design a character for him out of the rogue class. That seemed like the best option- he wanted to be fast on his feet, agile, mobile, and he wanted to attack only once per round with high accuracy and damage. A rogue with Improved Feint seemed ideal. Feinting would make his attacks more accurate, and grant him sneak attack damage, which would make them more damaging.
He HATED my idea. He didn't WANT to play a rogue! He wanted to play an iajutsu master! That's completely different than a rogue!
To this day I do not understand this attitude. If you can build a character that does all the things you want, then the game is flexible enough to accommodate your vision. The fact that you have to play a fighter, or a rogue, or a fighter/rogue to accomplish your goals shouldn't be important.
But I guess some people feel strongly otherwise. I'm not sure whether accommodating them is a good thing, or whether its just giving in to irrationality.
