My problem with the haywire is it is excellent against AV but useless against everything else. So i think i will try out the splinter cannons. I can definiatly see the benefit of the antitank it would provide in my list, but i think it has the staying power to ignore tanks at range. And go collecting VP in close combat.
I think the reroll to wounds will ensure i wont by tied up more then 2 close combat phases, unless im facing 30+ wounds.
I also considered adding the darl artisan formation instead of the corpse thief, it would definatly save me a lot of pts allowing all sort of other different toys
I've recalculater the pts and seen i have made som calculation flaws. So i have editet the first post with the slightly modified list (-4 chain snares, -2 darklances +syndriq's sump).
Lastly i will try the list tomorrow, if i have the time i will at some point write up a battle report.
