I am a townhall 7 with all troops level 4, other than dragons, healers, minions, and hogs, all of which are level 2. I need a good army composition to farm level 7 walls and a good range. I just took a break from farming, where I had been farming with either barch or BAG. I want to get maxed lvl7 walls and then get my king to level 5. Thank you in advance.
