So ... things that don't actually defeat enemies. Damage and control win battles, and Monks in 2014 are not good at those. These abilities you listed help you survive a bit, and that's it, and they're no better at that than, well, pretty much anything any other martial gets.
Survival is a big part of combat, especially at high level. Further this is not entirely true, several Monks can Nova a lot better than other 2014 non-casters and almost all of them can control a lot better than 2014 non-casters. The best control options for Monks are subclass abilities, not Stunning Strike. But Stunning Strike, as weak as it is, is still better than other non-casters have at this level.
Diamond Soul (both the proficiency and the reroll), Empty Body, Ki-fueled attack, Breath of the Dragon, Evasion, Aspect of the Wyrm, Exrplosive Fury, Shadow Arts, Shadow Step, Tipsy Sway, Blindsight, Ascendant Breath, Resistance, Unerring Accuracy, Touch of Death, Hour of Reaping, Mastery of Death, Touch of Long Death, Frightful Presence, Wings Unfurled, Empowered Arms, Fury of Healing and Harm (the Harm one), Hand of ulitmate Mercy, Wholeness of Body, Tranquility, Quivering Palm, step of the wind, Evasion.
In tier 4 all of these things are generally more powerful than Stunning Strike or Flurry of Blows. For the ones that are available at lower levels it is not true for all of them at lower levels.
Enough of them to know you're dead wrong.
So you claim. So how many is that?
