well, i've notified the league officials now because it does seem 99.9% obvious that my opponent made some mistakes in his list and with his army's abilities...
his 3 monat teams really hurt though. from memory here's what they looked like;
plasma rifle + missile pod + flamer
shield generator, tageting array, hard-wired drone controler w/shield drone. (maybe another toy or 2, never saw his list...)
it wasn't untill afterwards that i started thinking about it that i got the feeling i'd been had... (i'd been checking up about target priority because he messed that up too!)
but from what i can gather, his monats somehow has 5 hardpoints!
i'll let everyone know how this turns out. thanks again for the help,
cheers!
