Thats right. Give them the same rules as Bane Knights but with a skelletal Horse to carry them up the field faster. Maybe the cost 9 points for 3 multiwound models and 13 points for 5 multiwound models. The only thing I would restrict is BLT making more of them. Give them a Solo attachment that gives them something useful like magical weapons. The models would be awesome looking knowing how PP sculpts models and they would make Cryx even better. We could call them the Bane Bullet. How awesome would that be? Here is your opportunity to create the Bane Knight Cavalry. What would you give it? I suspect my idea might be OP, so how would you change it? Take away Vengeance maybe? What would you do to make these viable without them being OP?
