Second game, again 1000 points

BSB is generally a waste of time for Undead imo. 1 less model crumbling.. for half a Banner of the Barrows/Spirit Host etc.. no thanks. Could pinch yourself a few points there

Thank you, guys! 
I stuck with the Terrorgheist, as I was already playing when your answers came in.
The Terrorgheist was a threat that the daemons had no answer to. It even felt a little OP in the end: flank charging, screaming in the shooting phase, regular attacks plus thunderstomp, all while having T6. At this game size and without artillery, limited space or magic keeping it in check, it is certainly powerful. 
I'll write up report again with pictures. 

I wanted to include the Wight King as the BSB as it functions like a War banner for 10 less points. Your points about him are valid, though. His attacks never did much, when I lost combats, the saved model did nothing for me. A few times, the additional CR made me draw and win due to musician. Although, losing by one would also not have changed much. Certainly, the loss of the Necromacer to a failed LD test in my last game pushed me to have a LD re-roll, i.e. BSB. Also, the Wight King is tough with T5 and W3 and made my opponent waste some attacks on him. When we upgrade to higher points values and possibly include Lords, I may trust my LD a bit more again. 
During setup and the whole game I was very nervous about the army depending on the unlife of the naked T3 W2 Necromancer, again I hope that this will feel better when Vampire Lords become available. 
In hindsight, maybe the Banner of the Barrows and an additional unit of Dire Wolves or Spirit Hosts would have been better than the BSB, having more units would have been helpful in some situations. 
I will write up the report on Saturday or Sunday, stay tuned...
