Im relatively new to monk myself but i did play it a bit before the changes went live.
I find the changes to be fine, more or less. Though i would love to see the cooldown reduced on perfect balance. The beast skills should also be ogcds to make them a bit less clunky to cast. Of course anatman, six sided star and riddle of wind need updates as well.
Anatman id say basically needs to do anything useful that isn't as insanely niche as it is now. Perhaps making it some kind of defensive form during which you get lots of damage resistance and dodge chance, as long as you don't move or attack?
Six sided star should just be a normal gcd with a cooldown. Or even an ogcd with a cooldown.
As for riddle of wind, as someone else have suggested i would love to see this further reduce gcd time for all skills rather than increase the rate of autoattacks.

Things i definitely hope wont make a return that is the positionals. As much as enemies spin around they were a huge pain to actually use and more up to luck than skill in most cases. Sure you could pop the various skills that removed the positional requirement, but then whats the point of them in the first place? They were the main problem i had with monk before the changes and i find the class to be a lot more enjoyable without them. If they must make a return they should be less required and be something like a 20+ to potency when hitting the right position.
