The Illuminate are anti sniper
I was playing illuminate missions with the Diligence CS and it was so difficult. Only the AMR can one shot overseers and even then you only get 7 rounds. Just to kill overseers you need two shots to the head from the Diligence CS. One of the overseer types flies with the worst pathfinding known to man so tracking them is next to impossible, and the other has a shield which makes sense. Super Earth needs to start getting better precision guns. (I do love AMR I just don't want to be forced to use a gun I kill hulks with to kill medium units)
