Recommended/Tips for new season Necromancer?

Hello, I decided to try out Necromancer again, but this time going for seasonal without Hardcore setting. I am thinking about quickly levelling with a corpse explosion build I found on IcyVeins, but I am open to any recommendations if I want to farm levels quickly without any cheese or wasting too much time (difficulty, items, etc.) in Diablo 3.

I appreciate any help in that area, thank you.
