I'm a TH7 and have way more luck farming with Archers and Goblins (fancy name for that?). Most of the farming consists of full collectors outside of the walls, so goblins eat it up faster. I still manage to get at least 50% most of the time. So why is BARCH so popular? Maybe I just don't know how to do it correctly.
My range is usually Silver 2 to Gold 3.
