I got my copy of the new Kill Team game today and I'm excited to put together a kill team for the game. I'm going to re-brand my Eldar corsairs kill team for Shadow War: Armageddon for Kill Team. The rules for an Asuryani kill team give a bit more variety than the Shadow War version, allowing storm guardians (including the option to turn a storm guardian into a gunner!). I'm able to use even more of my old 1st and 2nd edition Space Elves/Eldar miniatures, though some of the weapon options (power glaive!) will require either chopping up an old Jain Zar (I have at least three, so that might not be a bad option) or using the plastic/resin ones from either the new dire avengers or Yriel. I know who my fusion gunner is going to be, though.
I'm a bit disappointed that warlocks, easily my favorite of the Asuryani units, aren't an option. These battle psykers often lead guardian squads into battle; and with both the Grey Knights and Thousand Sons having psykers (and GW implying that other factions will have access to psykers in later expansions), it just seems odd that warlocks were left out of the initial release. I'll get over it (especially if GW gives them to us later).
One of the things I really like about the Asuryani options is that you can opt for an all dire avenger kill team, all guardians (including pure defender or pure storm, if you please), all rangers, or a mix of these. Also, your leader could be anybody - you're not limited to a dire avenger exarch as you were in Shadow War: Armageddon.
Some of the more exotic items that were found in Shadow War: Armageddon aren't anywhere to be seen in Kill Team. At least, I haven't seen them yet. I'm talking about things like red-dot laser sights, clip harnesses, etc. The "customization" is mostly limited to what you can expect to find in the kit for the model type chosen, so it's basically similar to WH40K 8th edition. The real customization is in the overall composition of your kill team, the specialties chosen, etc.
Lore fanatics will enjoy the charts of Asuryani names.
I'm interesting in hearing others' thoughts on the Asuryani in kill team, as well as seeing your Asuryani kill teams.
