Y'know, usually I would agree with you...usually. But this guy doesn't know what he was doing and he threw an impossible encounter against us and started slaughtering our shared-world characters in Living ENWorld. Getting massacred by a GM who offers the party hints about how to decrease how much we are being slaughtered that actually aren't correct mathematically is not fun...in fact, being massacred by a totally superior force is never fun, and I would say the math is more fun than being killed (I'll only min/max character actions if the GM is going crazy on the PCs and otherwise I'm just along for the right). What about you?
