Good bossing builds?

I was wondering that with ascendancy now being released, what are some of the strongest builds for killing bosses? I'm looking to complete the challenges and a few of them require you to kill elite bosses and I was curious what would be good at that. I'm probably doing softcore since I ripped at 86 in hardcore and just want to finish off whatever challenges I still need without worrying about dying doing them.

i assume since you hit 86 in HC, you probably know that you asked a loaded question.

that being said, i have found that a larger percentage of bosses are easier with a ranged character

i ran a voltaxic ranger last season (doing it again this season) and was able to insta-melt a fuckton of shit. they nerfed the poison gem but you can still work around that single nerf.

The Slayer duelist ascendancy seems to be made for this.
