You completely missed my point. That's exactly the assumption you shouldn't be making. There is nothing a 16th level fighter is doing four times as often as a 3rd level fighter other than making attacks count. Raising your BAB, including the iterative attacks that go with it, means being more skillful. People who are more skillful at something are less likely to screw up catastrophically, not more. Fumble rules that don't reflect that are not reasonable rules.Lanefan said:There's no escaping the math that says a given random outcome is 4 times as likely to happen if it is given 4 times as many chances to happen.
