To be fair, that first one requires a minimum of three feats, and if you're not keeping up with your ASIs you're not really overperforming, so it isn't a problem until ~14th level. By that point most campaigns are dropping off anyway, and the challenges fall away pretty quickly. I agree that it is good on a monk, but monk doesn't really have the room to be picking up feats. But even if it could, monks can use the help. Would you consider taking this as readily as shield master?
