The problem with munchkins
is that they look at the game as a competition between them and the DM. Then the DM does something like throw out entire supplements like Relics and Rituals because one player insists on constantly exploiting every rule possible. And then the munchkin and DM get into a power issue, and the next thing you know there's a nightshade (that was in the module, btw), and then there's what could be if not a TPK, at least a 3/4-PK. And then the players that were playing the game and not being overly competitive with the guy who's got a pair of axiomatic dragonnes in the wings start getting frustrated because the game can be aimed at the average player in the group or the player whose character can wipe out the average player in one blow.
