I tend to lose him a lot in the early stages of the game, he is often targeted early although I am not sure why having never really gained a great deal of experience using him. I keep trying to keep him out of LOS so I can attempt to get him within the 2" range of his distraction aura but have so far not managed to get him this close, I maybe trying to be too direct with him even hugging terrain?
It had not occurred to me that he could be used for scheme running, I guess I have got used to playing The Cherub with Our Land, Accomplice and Rise Up!
