Or maybe it's a one and done trait now rather than a progressive trait and that got mixed up in translation by the interpreter?

"The gameplay element of stacking Greased Lightning will be done away with - So to compensate for that Chakras will be unlocked at a lower level." the quote, which seems a bit redundant with that already being gone. [2:21:51 on Live Letter Stream]
We'll have to wait for more info, but to me that sounds like Greased Lightning 4 (or it'll just be level 4 equivalent just called Greased Lightning) will just be a passive trait that gets unlocked when monk is unlocked, making it a job that just starts fast rather than something you have to unlock over time. And to make the job still feel like you're making progress, rather than unlock greased lightning levels 1-50, you'll get chakras. I wouldn't be surprised if it's sometime around level 30 or 35.
