which is the easiest to build and best character build for pvm?

im a total beginner and lookng for a solid build

(like hammerdin was on d2)

the entire game is pvm so there is your first hint

I started with a witch doctor using pets build. I found this great because to get your toughness and damage to a high level you need really good gear which takes a long time to aquire. But with a pets build you can focus on getting high damage output rares to do lots of damage while your pets take all the damage and do high damage like you. That way you can farm high torment levels without end game gear which will let you find more legendaries and end game items earlier.

literally 1 day

just play what ever the fuck you want

If it literally took just one day, I would have my carn and smk already. K?

I don't though because RNG drops are RNG.

Witch Doctor has probably been the hardest (longest) class to gear up for me.

From no gear at all to solo T6 is going to be one day if you get carried, maybe two if you don't and are unlucky.
