Shar'zul Worldeater Build advice

Just got a Sharzul Worldeater to drop for my Commando, and I’m wondering what set would be best to pair with it. I’ve been doing S&B but I’ve pretty much completed the build I was shooting for and after getting this lucky drop I thought it might be fun to reconfigure around it. I have the full Ulzuin and Justicar sets. Also looking for some build advice in general as far as devotions and the like.

I do also have a couple of Infernal Brimstone maces…is it actually better than Worldeater?

Fire Strike Commando with Justicar set is pretty great with Shar’Zul Worldeater. Shar’Zul Worldeater skill alone is better than Infernal Brimstone, it’s that good.

I would say go for cookie cutter FW Justicar build, it would be stronger than melee firestrike. Plus, there is a better weapon for melee Fire Strike (Archon maul).
