I also have recently been pondering the Kabalite Warriors being used like this. I like it a lot that the Haywire adds so much. the guy who is running in first place inthe ITC is a guy who plays in my meta. he has taken Imperial Knight play to a high level and Vincent Price, another heavy user of them has also shown me their virtue. having more ways to affect those threats seems like a no brainer. They are so imposing and the Avenger cannon can do so much good, that you really need the help when it becomes impotant. It's not cheap. but attacks on LD are also a common thing such as Psychic Shrieks from Hemlocks for example (my Orks stood their ground but did get hit by that three different times in one game and it was nerve wracking).
I also think the Kabalites can fit as an anti-tank answer in this sense: The drop pod armies and especially the insane PROPOSED Drop pod FAQ make an ability to pop a Drop pod kind of a bigger deal than it was before they announced that. For those who dont know or arent aware of this ridiculum, go check the proposed FAQ. It's absurd. Getting trapped behind them and helpless would not be good.
I am not a typical user of Kabalites. I've never liked them better than the Wracks that used to be troops choices and then later, I preferred the Coven tothe normal Dark Eldar anyways. So net result, I have used them scarcely. but now that I am using normal Dark Eldar more in games, they are making a comeback in my lists and my most recent creation (30 Striking Scorpions to accompany my Dark eldar to war) makes much better use of the Kabalites than any of my other lists would have.
anywho, thanks for posting this up. look forward to hearing more from you. Join us in the chat box, bottom of the main webpage, when you can!
