Level 25 harmonious here.
I can't show hard numbers but I have a feeling that our specials interrupt autoattack so if you spam them there are hardly any basic damage dealt. This unlike my ranger.
Nerve strike: useless on mobs higher in level since FD often fails and that is the only way to use nerve strike for me. I'm dreaming of Storm Stride working with Nerve Strike

Either that or adjust FD so it does not fail so often on higher mobs.
About damage. I seem to be very safe in a group, I can dish out as much damage as I can and rarely steal aggro from the tank, even if I'm higher in levels and not using Goading Slap. I don't know if this is intended but it feels wrong.
I also feel the crane stance is unbalanced, too much damage penalty for very little evasion gain.
I have stopped soloing with my monk, it's just not viable.
