Looking for advice with build.

Hi, I am making a Spectral throw, Doublestrike scion. Idea is to combine Pathfinder and Assassin ascensions.
Passive tree:Link

Attack:
Stacking attack and physical dmg.
Critical chance to increase dmg and refill damage enhancing flasks.
6 Frenzy charges generated with:

3 Power charges generated with assasin mark + blasphemy on non-boss fights
Hatred
Ice Golem to boost small boost critical chance

Defense:
Evasion
Life
Life leech + vaal pact
Acrobatics and dodge
enfeeble + blasphemy on tough fights.
cwdt + immortal call + blood rage

I am on lvl 71 and dont have the best gear but still feel i missing something. My hp currently is around 2700. I finished kitava but mapping seems harder then with other pre-made builds i played. I think i invested in many diffrent things and need to spec something out and get more life nodes. Can someone please advice me?
