The wounds mechanic really felt like it should have belonged to the Barbarian in my opinion. The monk has no way to regain endurance unlike the warrior, barbarian and paladin. I hope they make changes before the expansion to how the class functions and provide more class passive talents to increase DR in light armor. I would think some mechanism to minimize knockdown and engage multiple opponents/minimize flanking penalties would really be in line with the martial artist aspect.
Overall, I am really disappointed in the mechanical execution of deflection/damage reduction/speed penalties. The original posts that I saw suggested they wanted to normalize the damage to get away from the miss miss crit dead mechanics in the old D&D system but they didn't really accomplish that.
