Yeah, and you can even like using Google to pick your next move, when you are playing in your living room. So? Who the hell cares?
But in a tournament you will play by the rules, and the game needs to be designed with these rules in mind and put a system in place to make these rules have meaning and be enforced, rather than being a matter of self-restriction.
You are REALLY trying to be disingenuous about this, uh.
What's next, your good old "appeal to popularity"? Dismissing what forum dwellers and D&D nerds think because "The majority of the casual players will be happy anyway"?
