Against hogs, you've got two double bombs set inside between the bows ans ads where they can't easily be avoided along with a tough CC pull. Against lavaloonion, the ADs are inside enough and close enough to cover each other without being right on top of each other. ADs are protected by the air mines/bombs. Wiz towers are outside the range of the ADs so they attack loons as they come in. Ground bombs/springs are shaded toward the TH side in the event you get gowiped which shouldn't easily result in 3.
