Patiently awaiting Way of the Astral Self for 5.5

Title. As much as I had loved this subclass before, it is a bit of a glutton with your ki/focus and am hoping the reiteration of it is much more streamlined. I know I can still build one now with updated rules, but have not taken the leap yet. Was curious what everyone's impressions are with the updates and their experience with monk 5.5. Thank you!

You are probably going to have to keep waiting, because whatever they decided on for 5.5 is already done.   At best might end up being an optional class in an adventure module. 

They're still making subclasses. 

There's the question of whether astral self is sufficiently distinct from the new elements monk, so if they do revise it, it may be significantly different than the original. (Also, AFAIK, they haven't yet put a version into public playtest.)
