3.4 Viper Strike Occultist (WIP and looking for help)

I have been theorycrafting a Viper Strike Occultist Witch and was looking for some feedback from some more veteran PoE players to help max this build to it's full potential.

Here's the Path of Building pastebin of what I have so far :

Any constructive feedback would be greatly appreciated.

Update:

After more experimentation in Path Of Building I was able to push another 1.5 million dps out of the poison with trickster but I wouldn't have the aoe clear of Profane Bloom. So I was wondering if there's any good alternatives to it for aoe clear.
