I think you give fairly good advice, TheSheriff. A few remarks though:
- Not to nitpick but Horrors (as all Core Daemons) have Ld7 so Occam's would give them S7 and only the Herald would be at S8. Not big deal.
- Over at the Daemon Forums the majority of (especially competative) players seem to question why LoLife is oftentime described as a staple for Daemons, just as you describe it. I admit it looks good 'on paper' but after having it used a couple of times I have to say that at least a few other Lores (from the BrB) seem to be generally better choices (I'd say LoLight, LoShadow, LoDeath, LoBeasts, and even LoMetal - depending of course on the composition of your army).
For the MonoTzeentch Army I would really not recomend Life. First of all it's a defence Lore and Horrors don't need a boost to Toughness (what they need is to KILL stuff). Secondly, except for FleshToStone which is a great spell, most of the Lore has inefficient Casting Values (really) unless you have Throne of Vines up and running (which a savy opponant will not allow). Dwellers is cool but really only against S3 (or less) opponants.
I suspect that it is the attribute of LoLife that makes particularly non-Daemon players conclude that it's a 'must have'. It's good, I'll admit that of course, but again it's defense and a MonoTzeentch list is really lacking too much in the offensive department to afford such worries.
The advice on the LoDeath LoC is good, and I've seen that in action too being quite successfull.
