Toxic Rain Pathfinder ! Anyone mind looking at my build and giving me some pointers ?

Hi ! Could anyone give me some tips on what I should do next , far as gear and passive's ? I'm still using CA which I'm trying to phase out of but I'm not feeling the same AOE from TR . Got about 7ex to spend on an upgrade . Any help would be much appreciated .
