Help with my ST build.

Hey everyone :)

I'm curious on how i'm gonna be able to run more auras?
I can have 1, barely 2. I don't know if the tree i'm using is utter shit??

I'm a Spectral Throw build, and it's going quite alright.

Got 586 mana and using reduced mana gem with 2 of my auras. (haste and hatred)
But it's like i just can't get it to work?

Link to the tree i'm using, for some guidance, if anyone has a better feel free to post it.
