Current Necromancer can be built in a few ways. Tried that build in which you float 4 points into skeletons before lichhood, after which you switch heavily into ghouls. Didn't like it much. Dire Plague + Torture Souls is a pretty strong combo though.
Doombringer is simple and straighforward. Fearscape shift into the crowd and pull your devil trigger. Use the classic corruptor trick of "bring'em to hell" if you encounter something tough and don't forget that you have a ranged silence attack. My easiest Urkis kill, Temporal Warden aside. You also have a bunch of panic buttons which is nice, not as good as TW survivabiltiy options though.
Demonologist, a class that introduced tinkers before tinkers, also received a tiny rework while i was away. Recall that performing actual demon summoning was ill advised, now it appears to be very handy in a pinch. Certain demon bosses drop special demon seeds which not only grant one of a kind abilities but also allow you to effectively summon them later, very cool. Shame that they don't level-up.
Right now i am playing as Cultist of Entropy and... this fellow has a very different playstyle i must say.
As i understand it, you rely more on synergy between all of your abilities rather than select few talents. At the very beginning you suck very hard.
The moment you survive early game however... Let me just describe how my fight against the wierdling beast went down.
Hello, my wierd looking friend!
As you can see, i too have a million sustains active!
Here, let me generate some insanity and put this monolith to take your attention.
Here is your clone to keep your company, enjoy taking and giving less damage. Don't worry, your clone won't be here for long.
Let me put a whisper of madness on you. Oh look, another tentacled thing showed up! As long as that thing is alive you will further do less damage! Better take it out!
Here, let me put put a twofold curse on you.
Cacaphony to improve whisper of madness
By the way, do you know what happens when i put six magical debuffs on you? You see, i unlocked that oblivion tre- Oh Look, the Herald of Oblivion!
Nice knowing ya, my wierd friend!
