Monks do a fairly good chunk of damage. They can also do it multiple times per round. By 12th level, your unarmed attacks hit just as hard as the best weapons in the game (excluding firearms). They get to attack repeatedly and if you really hate their unarmed damage so much, they can have two weapons in their hands and be able to kick or elbow for unarmed strikes (actually in the description). They get all sorts of abilities for bad situations. The only downside to the class is no armor and the cost of AoMF. Given a high wisdom modifier, the monk will get as good an AC as any other class. AoMF enchants all of you. If you had claws or bite or so on. Monks can use just about any appendage, you enchant four or five weapon with that thing. It's cheaper when you think about it. They aren't any weaker than the other classes and don't need any special enchantments to make it cheaper, it's fine as is.
