Hi all,
After reading a lot of initial comments on necromancers being rather slow, I was wary to start leveling one myself.
While I do agree the movement speed feels lacking, especially coming from a rogue, the gameplay itself is so gratifying. Decided to level up a sacrifice build and forego all minions to try something off the beaten path.
Made my whole leveling plan/experience into a build guide (full tree is linked in the description): Necromancer Sacrifice Leveling Build 1-50 | Diablo 4 - YouTube
Let me know what you think 
I’ve got many more guides in my playlist, but recently settled on this new format of presenting the skill tree.
