You're unsure on 7th, eh? Well, Be'lakor benefitted from the edition change, making him better than ever. Jink is now 4+ (but snap shots your next turn)--so with shrouded, old Be'lly is getting a 2+ cover save always--and he no longer has even a witchfire in the form of Puppet Master, so no consequences. And additionally, he has the Shrouding power that can give another unit that can jink (say, Bikers) a 2+ cover save as well, if you feel so inclined. I think it's worth the points.
You are aware that FAQs let you take 2 blastmasters in a 10-NM squad, right? MORE BLASTMASTERS! I'd argue that those sonic blasters are somewhat wasted inside the rhinos, though--only blastmasters will be firing, and the turn you disembark the SBs will only be salvoing...
I don't know if you need a SlaLord, myself. The only difference is that the NMs would become super-scoring rather than just scoring. I mean, you could save some points on cultists... But you'd have to spend those points on the SlaLord.
