in one of the groups i used to play with, i was the voice of optimization, the voice of RP, and the voice of knowing the rules.

yeah, really dumb group. one of them, when we explicitly told him to walk up to a held ettin and do a coup de grace next round, charged and attacked (we had a houserule that if a held creature takes damage, he is no longer held.) his justification: "i only have an intelligence of 7, i don't know what a coup de grace is". we, of course, pointed out that even a wolf, Int 2, goes for the throat of a down opponent instead of just randomly biting. another one charged a door to attack it (not even an ubercharger, just randomly charged), and another tumbled into a wall. if i hadn't built all the characters and ran half of them, we never would have gotten anything done.
