Help me optimizing my SST Champion

I would appreciate a few tips on optimizing my Spectral Shield Throw Champion.
Overall, I'm very happy, but I'm sure there's still room for improvement.
I just don't know where.

I can't find a better weapon, not even PoB, which makes me wonder.
I also have no idea which armor would be an improvement.

About the gloves:
I used Southbound & Kaoms Spirit before, but I never really needed Berserk.
And without that, the current ones are much better.

So, what can I do?

Thank you in advance
