My friend has recently finished building his SCE army and it includes 9 Vanguard Raptors He sets them up in a line pretty close to his board edge preventing any tp behind them. In front of them he has one or two big long lines of Liberators, Paladins and Retributors. One of the debuffs he was telling me about was a -1 to hit shooting through a unit in front of his Raptors. These Raptors have buffed saves from hero etc I think almost a 3+ Or even 2+ now and they are doing mortal wound spam on 5+6's with another buff. How would you guys suggest countering this?
