Why 'slightly' defend an isolated TH
I understand that trophy hunters protect their town halls and I get why farmers leave theirs isolated but I don't understand why some people isolate their TH but then place it in the range of 1 cannon or a wizard tower for example. I came across 1 today where the TH was in the corner away from the base but it was enclosed in a wall with 2 cannons. Obviously they are still easy to destroy but I don't quite understand the point if there is one. Am I missing something?
