I'm going to assume you're either sleeping or playing ranked arenas yourself while Scold is streaming, but there's plenty of footage on his stream of double ranged. Some double lethality sniper, pyro merc / lethality sniper, and madness sorc / lethality sniper. He doesn't stream every time those comps have been used, but those comps are definitely in his videos somewhere.
You'll see very little double melee (aka double mara or mara with a full ap pt dps) being used on his stream excluding maybe a couple occasions. There's pretty much always one ranged in there at least.
