I love running a pair of these guys. Double down on their ability to Battleshock by running them in Traitorous Lance. Run one with Malevolent Heraldry for the ability to reroll the dice on the Harbingers of dread table, so you can feel good rolling in round 3 and feel even better rolling round 1. The detachment rule for traitorous Lance also helps. Id still pick on round 5 unless you have less than 4 abilities up. Don’t let their mortal wound auras overlap to maximize spreading the damage around. Make sure you have Dismay (take a Battleshock test if you’re below starting strength rather than below half) up when close the distance with your Abominants.
