one more thing. BARCH is as stated only used to farm outside buildings. you find bases with mines and pumps that are full and do a wave of barbs in a circle around base then a wave of archers around base in a circle. don't deploy in groups or mortars and wiz towers will destroy them fast. the key to BARCH is spreading out the attack so as to negate the splash damage of mortars but be ready to lose some trophies using this strategy. you will occasionally get 50% victories but you will go up and down in trophies. if your goal is to farm this should not be a problem.
