EA R'lyeh is baaad. However, that's pretty obvious to most people. What I'd really like to see is Atlantis having more spells, and the ability to use blood on both land and sea would be extremely thematic, and fun. Not too overpowering either, because there aren't many blood-sites (if any) in the ocean, so it'd be harder for them to collect bloodslaves-and they'd probably need more than a human nation would, since they maybe wouldn't be as familiar with the most efficient rites.

EA R'lyeh would be better if it had more strong national astral spells, and maybe some earth, since they do live in mud. A little blood would be fine, but I don't really see them being a "blood-nation", as opposed to Atlantis. I can definitely see Atlanteans sending raiding parties to the surface and dragging back screaming victims to use as bloodslaves. They're already maybe breeding with surface-dwellers once in a while for kicks, and they're weird and creepy and evil enough to be very in to nasty demonic rituals. I just don't see the same thing nearly as clearly for EA R'lyeh. They're too alien and strange for blood-magic. They might use slaves for drudge-work, but not for blood magic, except possibly in a very limited capacity-maybe a mutant strain of aboleth has access to 1 blood as a random?.
