SSF HoAG build advice

Good Morning :)

So. I have played a lot, but never gotten very far. I enjoy SSF and decided in order to actually get somewhere near the later stages of the game, I will play standard SSF instead of always making new character in the current league.

​

My strongest build at the moment is this HoAG Guardian from past leagues. POB (community version): https://pastebin.com/r2H127BL

This can clear Tier 8 maps relatively comfortably, but starts dying in higher tiers relatively often.

Now my Question is this. Is HoAG without Arakaalis Fang still a viable build to try and push further? And if so, can you give me some advice on what to improve with the build.

​

If this is not the build to continue pushing, could you recommend a build that is suitable for farming breaches in SSF? I own some uniques, for example a Devouring Diadem, but nothing crazy.

​

Thanks!
