I should be a little bit better with my DHs now since I've switched 2 DHs to pure fire with Immolation Arrow. The 1 DH that had SoJ without socket now has a gem, so that will add up too.

I don't think Strongarms stack like that, but if it's the case, then why go with Wizards that have cooldown on that skill, just go with Stampede Crusaders. 4 of them will proc Strongarm's like there's no tomorrow. That's another build I'm working on too. The main attack knockbacks and stuns, so u can imagine everything will be CC and debuffed. And Crusaders have the highest toughness and with Akarat Champion they are completely immune to CC. Stampede stuns even Rift Guardians and with 4 Crusaders we are talking about permastun of everything.

I'm working on this too but will take me a while I guess, tho I got most of the items already.
