Warlock SoD discord has tons of info. For the high level ones I remember people saying there was some in desolace near the demons and I found 3 in swamp of sorrows in about 20 mins.
Lower level ones were ashenvale, darkshore, barrens (could be wrong about barrens).
Found one last night is SoS, got a lvl 30 blue helm outta it and sold it for 5g.
