I have yet to play a game of AOS, but I'm currently building a slow grow Gloomspite army (and I'm way behind already having only 300pts painted when the group is playing 750pt games).
My projected 1000pt build is thus..
2x20 stabbas 260
10 boingrot bounders 200
5 fanatics 140
mangler squigs 240
It's only 2 battle line but we're not requiring 3 until we go to 1250pts.
My plan from here is to expand my goblins, upgrade the mangler to a boss, add some snufflers and then see what else to do from there. I do want soem Stone Trolls at some point.
