Hello,
For the past several months I have focused strictly on walls (currently th9). My strategy has been farm gold/elixer buying Lv 8 walls at 500k gold and Lv 9 at 1 mil elixir. I also upgrade troops in between but they're 10-12 day wait times. I am nearing 100% lv 8 walls and have about 15% lv 9 walls. What level wall is a good place to stop to focus on defensive buildings?
