I think a waystalker with bow of loren is being over looked, yes the waystalker can shoot twice, but what he can do with the bow of loren is shoot twice and ignore armour saves at the same time. Doesnt sound that great but combined with sniper you can force heroes out of units to hide, combine this with glade guard with trueflight or a scout unit with trueflight and its not safe for that hero to be out on their own either.
