Monks have high to very high in all 4 categories--health, endurance, accuracy, and deflection. Wounds and the abilities they allow are just icing on top of that. The problem is thinking of them as AD&D monks--like several classes here, they play very different from their AD&D classes of the same name. Chanters, for example, do very well in full plate since it doesn't slow down their songs, whereas the stereotypical bard doesn't wear more than light armor. You just have to get past your idea of what the class should be and play it for what it actually is.
