I'm going to give this a shot and hope not everybody just left by now...
what units do you field in AOS
how big are your units?
and how do you play them?
I have played one game AOS with VC against chaos and won
i must say we used some add rules, limits on monsters, hero's etc. (Age of Sigmar: Competitive Rules Doing the Rounds - Bell of Lost Souls) we changed the hero + monster = both to only hero
-5 blood knights
-3 spirit hosts
-36 skeleton warriors with ancient spear and crypt shields
-26 grave guard
so i had 100 wounds and 82 models
vamp lord went with skeletons, coven throne in the center, GG on the other side bloodknights and spirit hosts on one flank and varghulf on the other
must say that 30+ skeletons + lord command ability is pretty hard (4 attacks with +1 to hit) and spears gave me more range the amount of attacks was crazy
blood knights where very good to!
he killed 1 each round but that one always came back!
wight king went with grave guard for the bubble, they really are good to for the erm, amount of wounds... (so weird way to make your lists)
i summoned 2 extra varghulfs who did pretty fine to
one hold up 25 beastmen gors or ungors!
the spirit hosts are an auto include in my lists from now on... 3 wounds but 6 attacks and every 6 to hit is a mortal wound!!
very good against high armored units and monsters!
