it may be worth it, overall if you own edo tensei hashirama and asuma wb full skillbroken.

the first to max, imho, is the 3rd passive, since both at +2 and at y+1 is extremely good.

the +2 version works good with chakra coordination and natural draining of wind main and also with nature energy gathering of water main.

the y+1 version make him selfstacking a lot, overall if you manage to bring the chase to +2 (it's up to 28% nin/atk per round LOL).

then comes the mystery imho (at y+1 suppresses super armor while at +2 apply immobile to akatsukis that are everywhere).
