Well, while we're on the topic of Marro Armies, I like-
Su-Bak-Na- 160
Nagrubs x2- 60
Stingers x3- 180
Dividers x2- 100
500 points, 20 hexes. I think.
Anyway, Dividers can screen for the Stingers, and Su-Bak-Na kills anyone too tough for the Stingers to take down (in short, nobody). You have to keep those Nagrubs close to the Hivelord though, 'cuz if he goes down, those Dividers won't survive worth a
. However, if they only have to get a 16 or higher, with a little luck, this army kills all in it's path.
