Some fluffy tormented-souls construct or torment-engine would be a nice addition, but I believe that we will end up without a big monster. Our tactics and army flair is different than others'. We don't need big monsters, because we do not fear them. Our poisoned shots make short work of Trygons, Riptides and even Wraithknights. If I am not mistaken, statistically it takes 9 splinter rifle shots to take a wound from 3+ save unit. Which is 45 shots for 5W monsters of ANY Toughness. Add some blasterborn or Dark Lance and the number of firepower needed really gets down. I would be glad to see Mandrakes/Hellions fixed instead of having a monster.
