When attacking you have the opportunity for trophies and /or loot,but when defending you can either win or lose trophies but you always lose loot( quantity does vary)... How about when defending if the attacker is unable to get any stars the loot that is at stake goes to the defender
This would make the game unfair. what about abandoned bases where you only attack the collectors and almost never get a star? 250-300k each you didn't get.
