With the new edition on our doorsteps, I've been trying to think about how to maximize the advantages of being able to take allies for daemons (and chaos space marines -- but I'll leave that for another day ... although ork stompas did cross my mind).
So, I started thinking about Fateweaver and his special ability: he can have his friends re-roll saving throws. What could be exploited with this?
The first thought I had was to marry him up with something that had good shooting. That connected me to the idea of having multiple units of obliterators. Perhaps up on the roof of a piece of scenery that we bought as part of the new force organization chart?
Alternatively, perhaps some Tau allies (not best buddies, but as I read it, could still be affected by Fateweavers rules -- let me know if you disagree) on the same roof could also work well. Railguns (etc.) could be very appealing there!
Ork allies might make for an entertaining alternative. Not exactly known for their shooting, but in vast numbers, that could make for a fun army list! The same might be said for Imperial Guard.
There's too many thoughts zooming around my head to think about with allies. I think some testing is going to be needed before a final list is built for my 6th edition version of chaos armies. But the prospect of allies are certainly making me think -- they're going to be a great innovation for 6th!
