I agree with a lot of what's been said, especially about unarmed strike scaling & stunning strike. Back in 3.x I didn't care when a god wizard type could shut doown monsters or trivialize an encounter for a reason. Specifically those reasons were that I could make a god wizard with a few levels under his belt at the peak of his game fear for his soon to be very short life with something like a zombie climbing out from some debris or even skeleton archers far enough away from the main show to avoid being caught in the thick of things. the same is not true of good ac good HP good damage monks who just mutter "I used all my ki on stunning strike/flurry last fight, lets take a short rest" & get eager agreement from the warlock fighter to repeat it every fight. If monk is supposed to be a controller then it needs to present as one rather than a hybrid controller/striker/offtank.
