Just getting back into 40k and returning, to my great joy, to the new Dark Eldar. These guys not only look absolutely fantastic now, but the rules for each and every unit is amazing (barring a few personal annoyances such as not being able to give a lord a bike or skyboard anymore) Wanted to throw up a list I've been thinking about that has a lot of flavor imo. Was hoping to fit in some Scourges but want to see if the Hellions can do the job I hope they can do. It is a bit different then a lot of lists I've seen and I'm not entirely sure of the general state of 40k army builds at the moment. I know I'm lacking in the anti tank firepower a little bit but if played correctly can be plenty.
One concern I do have for this list is the Cronos Engine. Everything here is exceptionally fast minus this one particular model. I'm curious to get some advice on how to utilize him to the greatest effectiveness with this list. So please tear into it as any good Dark Eldar would
