Here’s a PvP meta build that fits your description:
http://metabattle.com/wiki/Build:Necromancer_-_Traditional_Terrormancer
As for PvE: max direct DPS is the meta like it always has been. Necromancers are the worst class in group PvE because of their near nonexistent group utility and low power damage (though with frost spirit stealth-nerfed to oblivion, maybe it’s tied at bottom)
So condi bunker (as what you’re looking for is called) is the worst possible build for PvE because berserker max DPS (sometimes with a bit of assassin)>>>>>>>>>>>>>>>>>>>>>> anything else except in very niche situations.
If you do want an idea of what is considered the best type of build for Necro PvE (though no min-max group EVER has necros), I’ll link it below, though it’s the opposite of your wanted build description:

I love necromancer, but it’s my bank character because they always get the very short end of the stick.
