You could try a Twister/summon build for your wizard and for the hirling the melee skills aren't a big deal, but you want recall (summon proc) and apocalypse (mythic skill) which summons 3 meteors from the sky that when they land they turn into 3 furies (basically like minions kind of). Also make sure to have Cooldown maxed.
So the idea is to spam twister while your warrior and minions tank. There could be some sets that make a summon build better, or that allow you to have more minions, but I can't remember at the moment.....there's def more things I could do with my build, but as long as I'm killing everything fast np, I don't worry about it so much atm.
Sometimes it can be tough to hit stuff with twister but eventually the mobs will cluster in one line, and you can blast them with twister from a far.
