Looking for advice on a Scion Archer Assasin / Raider using CI.

Hi everyone. This is my first attempt at a build using what I've learned over the last month or so of playing. Many of the ideas come from Neversink's Tornado-shot guide, my thanks to the author.

I'm trying to build a crit-based physical bow user who switches fairly late-game to CI. Scion is being used as the start point so that I can take the Assassin and Raider ascendencies. The build is going to be solo self-found only, so I'm trying to avoid trading completely.

I'm looking for help / advice trimming the fat in the builds, as well as streamlining gem choices, and gem/passive interactions. Thanks in advance!
