An idea for a {Crit - Fireball - Pledge of Hands - Softcore} build

Yo' tbh i don't know if this is where i've to post this thread but i'll do it anyways expecting some feedback and ideas, that would be awesome!.

My idea is to create an Scion with the next aspects:
- Scrubco... i mean Softcore
- It has to be crit (scrubcore)
- It has to be Fireball (of course i'll link Increased Critical Strikes Gem)
- It has to be Pledge of Hands (5L, cant afford 6L)
- It has to be Scion
Why?



I did this skilltree (i just want somenthing with 4,6-6k or more total life):

Maybe Elementalist instead of Inquisitor?


I never did a build or tried to do it, until now, please have that on mind :)

Therefore sorry for my english and i'll expect feedback
