[QUOTE="Storminator, post: 2150863, member: 305"] In your chart you have done the algebra to move all operations to one side of the ">" sign, and you have solved it for enemy AC. If you read the rules right out of the book, and apply them without manipulation to make the chart, you have to do math on both sides of the ">" sign. You have to subtract AC off Thac0, and you have to add your bonus to your d20 roll. The essence of the argument between Thac0 and 3e's attack bonus system is who solves the equation for AC. Does each individual player do it, or does the game system do it? In 3e the game system does. In 1e the game system did the math and made a lookup table. In 2e individual players did the math. The only thing left to resolve is which of those methods one prefers, and how much you care at all. Oh, and apparently, we need to kvetch about cheating. PS [/QUOTE]
