Monk changes are ridiculous. Instead of changing monks based on your 'internal testing', try listening to the players reasoning and balancing it around what they have to say. After all, they know a lot more about the game than you guys do. If you really think that nerfing the entire monk class just because at level 30 they have great dps is a reasonable excuse to nerf the whole monk class as a whole then you are, dare I say, delusional.
Also, not saying anything on the matter and ignoring your players is really not the way to go about the situation.
Leave monks alone, listen to your players. You guys are clueless
