Show me one rule that you have to follow and you will be wrong. In D&D not one rule is set in stone such that the DM cannot change it if he wants. All of them are examples. ALL of them.
I want to refocus on this for a second.
Because this entire line of conversation about my barbarian character started because of exactly that. I posted a character I had played, and enjoyed, as an example that your class is not the entirety of your character. That in fact, it is perfectly reasonable and in fact can be an good character, to play something that is not the stereotype of the class.
And I was told I was wrong.
You have told me I was wrong.
You have told me, that I broke the rules, because my barbarian could not be civilized. That being civilized broke the rules of the barbarian, and here was the text to prove it. In fact, I think you were the poster who said that if I was so desperate to change the rules of the class to play a knight, I should have just changed the name as well, and called it "The Angry Knight"
Now, here you are, less than a week later, telling me that if I showed you a rule that I have to follow, that I would be wrong. That all of the rules are mutable. That all of the rules are changeable. That, I am perfectly within the realms of the game, to change anything I want in whatever way I want.
So, is that the big point you want to make? "You broke the rules, but it is fine because the rules don't even matter anyways?" Is that where we end this conversation at?
Because, the more I dug down into "if these are the rules then it is more than my concept that doesn't fit, all of these more standardized concepts don't fit. If these rules are so hard lined, then why is there even a choice because these concepts don't fit either" the more you seemed to backpedal. This one is an exception, that one is just a theme, these are just examples.
The rules don't matter.
Well, if the rules don't matter, then why did you use them to tell me my concept was wrong? That I was not playing a barbarian at all, I was playing "The Angry Knight"? If you don't think there are any rules, why did you use them to put down my concept and say that it was against these rules?
