Well, let me explain... I didn't really take to DoK more due to the lack of their unit diversity, and in more combination with their play-style. It's not that they hit hard and fast (as I love idoneth, who do that well), but basically they are a horde army that has only a few units... and even fewer of those units are considered worthwhile. Doomfire warlocks are only okay, Medusae is only okay, Blood Stalker (Melusai Archers) aren't that great, Lifetakers are situational... what does that leave us with?
A not very interesting roster, in my opinion.
I love the Drukhari because of their labyrinthine options. There are three different distinct ways of playing them, and playing them well. Then you can get even more unique combinations by combining those play-styles into different ones.
I don't mind the glass, lightning fast cannon as a play-style.
While I agree that there is some crossover between DoK and DE, I think there's a lot of differences that make DE quite a different case.
Appreciate both of the opinions given, guys
