I think that if a character roleplays a thought and clearly states that it is a thought, then NOONE will know about it. Not being able to roleplay one's thoughts takes roleplaying out of the equation entirely. Roleplaying details about a characters thoughts and other details about the character just makes the character more real. How many novels have you read in which there is not one description about a character or the thoughts that run through their heads? Explaining thoughts is a way to get insight on the character.
Roleplaying makes the game more real, more fun. Developing the characters through a roleplay brings life to them, whether by roleplaying thoughts or by describing ones actions. It is what makes the character who he is. Take that away and there is no meaning to ever roleplay. Take away the details about the character, and he becomes a name on a webpage followed by his stats. And that is not what battlemaster is.
