[The Emerald Host - Welcome to the Danger Zone]

So atm we don't know if Melkor is going to be classified as a named character or not. The fact it has it's name rather than just KoSoS on the battalion tax might mean that it is a named character, with a different command ability. We don't know yet.

Personally the fact only the KoSoS gets to use the free CP is what puts me off. I'd much rather it be any of the units on the warscroll that could use it, especially as the hexwraith battalion will only let you pass off wounds onto the general, so if Melkor is your general then the dreadblades aren't teleporting themselves and other units around the board, which makes the dreadblade tax of that battalion even worse. 

They have some merit but they are also massively underwhelming as they currently are. Maybe the WD will have more than is yet to be show in the leaks.

Looks good but agree with previous comment, change the command ability to give deathrattle unit +1 attack or ignore all minus to hit modifers for attacks they make or something that can be useful and warrant actually using it.
