I did a while ago, when KWing alpha had Surge: Arthropod rank 2, it was a lot of fun. I had things like Rolling Shriekers, Sand Spitters when they were melee, Broodmothers, Soulcrawlers, Kwing Alphas, Protect Nest other stuff i cant remember.
I suppose I'll do it when I get my hands on a little more Poxbox point. Can't afford KWing alphas atm. Sounds like a fun bg.
Kwing Alphas dont have the Surge Arthropod no more so itll lack that strength but there has been tons of changes since then so no idea how strong it can be currently. I think i had Cinderpedes.
