How walls impact defensive players?
As I've upgraded walls I've noticed (i) tougher players attack me easy attackers pass me - so i loose defence cup winning opportunities (it takes longer to be attacked so people must be skipping me) and (ii) my cup losses seem bigger (do higher level wall bases offer more cups to attackers who win?) - As a defensive player at what level walls should you stop upgrading? Do high level wall bases offer more cups to attackers?
The more interesting question is
At what level should defensive players stop levelling walls - go to high and u scare off the easy attackers
