Awesome guide. I have tested Hinom in SP and came with close conclusions but your guide covered all the points I've misses, which is great
I've taken a W9, E4 bless with dragon and good scales, the bless makes Rephaim and Melqart expand like crazy.
I've used regular scouts/commanders for blood hunting and it worked well but I think using three Kohens with SDR will yield many more slaves.
Ba'al is ridiculous, I couldn't come up with enough ways to use them.
Your suggestion of using lesser horrors is very useful.
I think 1v1 this nation is top tier in game if not first place. How it would stand in MP is totally another issue though. I'm against changing something drastic in order to balance them, if anything the dawn guards could be made capitol only or the nation can get a 10-15% price increase across the board.
