I was able to get my first game of AoS in today with a Goblin army I just started putting together. It was also my opponents first game and they where playing Deamons, it was a 40k army but now those round bases work both ways.
1000 points of Goblins.
Grot Warboss
Grot Shaman
Grot Shaman
40 Night Goblins with spears
40 Night Goblins with bows
6 Fanatics
1 Giant
My opponents army was something like
2 Deamon Princes
2 units of 10 deamonettes
Slaneesh Herald on Chariot
20 Chaos warhounds
3 Blood Crushers
The Deamons had no magic and no shooting. It was a great game and turn 2 it looked like my opponent was going to take it. But my Spear unit with mystic shield proved very stubborn and held long enough for me to whittle down some of the other threats. The Giant was fun and my Grot Warboss killed a Prince so that was awesome. The Deamon player had some good luck with the slaneesh chariot before the giant got to it. The Blood Crushers where very underwhelming. They had a lot of wounds and good armor but not much damage output.
I also just signed up for Annihilation 5 so watch for Night Goblins skulking about.
