I've played two games with my Nurgle Gooey Host with AoS rules so far ... still very resilient, the Plaguebearers still hit as well as a soft, wet sponge (or my dice need some burning), Nurglings are very fun, Heralds are good support units, Beasts are a bit better solo but I didn't try a big unit of them yet, and Great Unclean Ones mash apart other Heroes but get munched by big units.

I didn't try the Plague Drones yet, nor a "big army", we're still trying to warp our heads around the new rules and possibilities with my gaming group, but I can say this : stay away, preferably at least a continent away, from any player that use Stonehorns ...
