Staff Crit Wild Strike Scion (need input)

First it started with me wanted a Wild Strike build. But then, after doing some research, apparently crit builds are generally a way to go with Wild Strike.

This is what I roughly have for the end-game:

Just want suggestions on how I could improve it.

Also, I made this character for the one-month league. How viable is this build without any rare uniques?

EDIT: Alternate version that takes the Blunt Trauma cluster and adds some extra Mana:

i dont think this is viable, you have way too low life in your tree and many weird points

wild strike needs high aps like daggers or claws with claws being great to sustain mana/life
i tested it myself with 2h swords and its a pain in the ass

if you like wild strike check out the existing guides here, if you want to play with a staff (i love them ^^) go for another skill
