Need Feedback on Crit staff build

Heya guys.

I am currently trying to make a crit staff build to go along with the new unique Hegemony's Era.

Things that i needed to get with the skill tree:
Knockback on crit
Powercharges
minimum 180% life (I play Hardcore)

So anyone have any corrections or experience with this kind of build?

Also, which skill should i use??

hey m8,

interesting concept - I am planing to do something similar with a sweep templar (just for the lulz).

What is your main source of defense besides life?

I was thinking about going into the duelist area for master of the arena and some armor & evasion + IR instead of shadow, but obviously you would lose a lot of crit...
